- = Changes to templates =
90
- None necessary! Relevanssi uses the standard search form and doesn't usually need any changes in the search results template.
91
 
92
  If the search does not bring any results, your theme probably has a query_posts() call in the search results template. That throws Relevanssi off. For more information, see [The most important Relevanssi debugging trick](https://www.relevanssi.com/knowledge-base/query_posts/).
93
 
94
- = How to index =
95
- Check the options to make sure they're to your liking, then click "Save indexing options and build the index". If everything's fine, you'll see the Relevanssi options screen again with a message "Indexing successful!"
96
-
97
- If something fails, usually the result is a blank screen. The most common problem is a timeout: server ran out of time while indexing. The solution to that is simple: just return to Relevanssi screen (do not just try to reload the blank page) and click "Continue indexing". Indexing will continue. Most databases will get indexed in just few clicks of "Continue indexing". You can follow the process in the "State of the Index": if the amount of documents is growing, the indexing is moving along.
98
-
99
- If the indexing gets stuck, something's wrong. I've had trouble with some plugins, for example Flowplayer video player stopped indexing. I had to disable the plugin, index and then activate the plugin again. Try disabling plugins, especially those that use shortcodes, to see if that helps. Relevanssi shows the highest post ID in the index - start troubleshooting from the post or page with the next highest ID. Server error logs may be useful, too.
100
-
101
- = Using custom search results =
102
- If you want to use the custom search results, make sure your search results template uses `the_excerpt()` to display the entries, because the plugin creates the custom snippet by replacing the post excerpt.
103
-
104
- If you're using a plugin that affects excerpts (like Advanced Excerpt), you may run into some problems. For those cases, I've included the function `relevanssi_the_excerpt()`, which you can use instead of `the_excerpt()`. It prints out the excerpt, but doesn't apply `wp_trim_excerpt()` filters (it does apply `the_content()`, `the_excerpt()`, and `get_the_excerpt()` filters).
105
-
106
- To avoid trouble, use the function like this:

118
- = Combining with other plugins =
119
- Relevanssi doesn't work with plugins that rely on standard WP search. Those plugins want to access the MySQL queries, for example. That won't do with Relevanssi. [Search Light](http://wordpress.org/extend/plugins/search-light/), for example, won't work with Relevanssi.
120
-
121
- Some plugins cause problems when indexing documents. These are generally plugins that use shortcodes to do something somewhat complicated. One such plugin is [MapPress Easy Google Maps](http://wordpress.org/extend/plugins/mappress-google-maps-for-wordpress/). When indexing, you'll get a white screen. To fix the problem, disable either the offending plugin or shortcode expansion in Relevanssi while indexing. After indexing, you can activate the plugin again.

  You can find solutions and answers at the [Relevanssi Knowledge Base](https://www.relevanssi.com/category/knowledge-base/).
127
 
 
 
 
128
  = Relevanssi doesn't work =
129
- If you the results don't change after installing and activating Relevanssi, the most likely reason is that you have a call to `query_posts()` on your search results template. This confuses Relevanssi. Try removing the query_posts call and see what happens.
130
 
131
  = Searching for words with ampersands or hyphens doesn't work =
132
- Please read [Words with punctuation can't be found](https://www.relevanssi.com/knowledge-base/words-ampersands-cant-found/). This is a Relevanssi feature, but you can circumvent it with a simple filter function.
133
 
134
  = Where are the user search logs? =
135
- See the top of the admin menu. There's 'User searches'. There. If the logs are empty, please note showing the results needs at least MySQL 5.
136

137
- = Displaying the number of search results found =
138
-
139
- The typical solution to showing the number of search results found does not work with Relevanssi. However, there's a solution that's much easier: the number of search results is stored in a variable within $wp_query. Just add the following code to your search results template:
140
-
141
- `<?php echo 'Relevanssi found ' . $wp_query->found_posts . ' hits'; ?>`
142
-
143
- = Advanced search result filtering =
144
-
145
- If you want to add extra filters to the search results, you can add them using a hook. Relevanssi searches for results in the _relevanssi table, where terms and post_ids are listed. The various filtering methods work by listing either allowed or forbidden post ids in the query WHERE clause. Using the `relevanssi_where` hook you can add your own restrictions to the WHERE clause.

- ` AND doc IN (' . {a list of post ids, which could be a subquery} . ')`
149
-
150
- For more details, see where the filter is applied in the `relevanssi_search()` function. This is stricly an advanced hacker option for those people who're used to using filters and MySQL WHERE clauses and it is possible to break the search results completely by doing something wrong here.
151
-
152
- There's another filter hook, `relevanssi_hits_filter`, which lets you modify the hits directly. The filter passes an array, where index 0 gives the list of hits in the form of an array of post objects and index 1 has the search query as a string. The filter expects you to return an array containing the array of post objects in index 0 (`return array($your_processed_hit_array)`).
153
-
154
- = Direct access to query engine =
155
- Relevanssi can't be used in any situation, because it checks the presence of search with the `is_search()` function. This causes some unfortunate limitations and reduces the general usability of the plugin.
156
-
157
- You can now access the query engine directly. There's a new function `relevanssi_do_query()`, which can be used to do search queries just about anywhere. The function takes a WP_Query object as a parameter, so you need to store all the search parameters in the object (for example, put the search terms in `$your_query_object->query_vars['s']`). Then just pass the WP_Query object to Relevanssi with `relevanssi_do_query($your_wp_query_object);`.
158
-
159
- Relevanssi will process the query and insert the found posts as `$your_query_object->posts`. The query object is passed as reference and modified directly, so there's no return value. The posts array will contain all results that are found.
160
-
161
- = Sorting search results =
162
- If you want something else than relevancy ranking, you can use orderby and order parameters. Orderby accepts $post variable attributes and order can be "asc" or "desc". The most relevant attributes here are most likely "post_date" and "comment_count".
163
-
164
- If you want to give your users the ability to sort search results by date, you can just add a link to http://www.yourblogdomain.com/?s=search-term&orderby=post_date&order=desc to your search result page.
165
-
166
- Order by relevance is either orderby=relevance or no orderby parameter at all.
167
-
168
- = Filtering results by date =
169
- You can specify date limits on searches with `by_date` search parameter. You can use it your search result page like this: http://www.yourblogdomain.com/?s=search-term&by_date=1d to offer your visitor the ability to restrict their search to certain time limit (see [RAPLIQ](http://www.rapliq.org/) for a working example).
170
-
171
- The date range is always back from the current date and time. Possible units are hour (h), day (d), week (w), month (m) and year (y). So, to see only posts from past week, you could use by_date=7d or by_date=1w.
172
-
173
- Using wrong letters for units or impossible date ranges will lead to either defaulting to date or no results at all, depending on case.
174
-
175
- Thanks to Charles St-Pierre for the idea.

184
  = Did you mean? suggestions =
185
- To use Google-style "did you mean?" suggestions, first enable search query logging. The suggestions are based on logged queries, so without good base of logged queries, the suggestions will be odd and not very useful.
186
-
187
- To use the suggestions, add the following line to your search result template, preferably before the have_posts() check:
188
-
189
- `<?php if (function_exists('relevanssi_didyoumean')) { relevanssi_didyoumean(get_search_query(), "<p>Did you mean: ", "?</p>", 5); }?>`
190
-
191
- The first parameter passes the search term, the second is the text before the result, the third is the text after the result and the number is the amount of search results necessary to not show suggestions. With the default value of 5, suggestions are not shown if the search returns more than 5 hits.
192
-
193
- Relevanssi Premium has a much better version of this feature.
194
-
195
- = Search shortcode =
196
- Relevanssi also adds a shortcode to help making links to search results. That way users can easily find more information about a given subject from your blog. The syntax is simple:
197
-
198
- `[search]John Doe[/search]`
199
-
200
- This will make the text John Doe a link to search results for John Doe. In case you want to link to some other search term than the anchor text (necessary in languages like Finnish), you can use:
201
-
202
- `[search term="John Doe"]Mr. John Doe[/search]`
203
-
204
- Now the search will be for John Doe, but the anchor says Mr. John Doe.
205
-
206
- One more parameter: setting `[search phrase="on"]` will wrap the search term in quotation marks, making it a phrase. This can be useful in some cases.
207
-
208
- = Restricting searches to categories and tags =
209
- Relevanssi supports the hidden input field `cat` to restrict searches to certain categories (or tags, since those are pretty much the same). Just add a hidden input field named `cat` in your search form and list the desired category or tag IDs in the `value` field - positive numbers include those categories and tags, negative numbers exclude them.
210
-
211
- This input field can only take one category or tag id (a restriction caused by WordPress, not Relevanssi). If you need more, use `cats` and use a comma-separated list of category IDs.
212
-
213
- The same works with post types. The input fields are called `post_type` and `post_types`.
214
-
215
- You can also set the restriction from general plugin settings (and then override it in individual search forms with the special field). This works with custom taxonomies as well, just replace `cat` with the name of your taxonomy.
216
-
217
- If you want to restrict the search to categories using a dropdown box on the search form, use a code like this:
218
-
219
- `<form method="get" action="<?php bloginfo('url'); ?>">
220
- <div><label class="screen-reader-text" for="s">Search</label>
221
- <input type="text" value="<?php the_search_query(); ?>" name="s" id="s" />
222
- <?php
223
- wp_dropdown_categories(array('show_option_all' => 'All categories'));
224
- ?>
225
- <input type="submit" id="searchsubmit" value="Search" />
226
- </div>
227
- </form>`
228
-
229
- This produces a search form with a dropdown box for categories. Do note that this code won't work when placed in a Text widget: either place it directly in the template or use a PHP widget plugin to get a widget that can execute PHP code.
230
-
231
- = Restricting searches with taxonomies =
232
-
233
- You can use taxonomies to restrict search results to posts and pages tagged with a certain taxonomy term. If you have a custom taxonomy of "People" and want to search entries tagged "John" in this taxonomy, just use `?s=keyword&people=John` in the URL. You should be able to use an input field in the search form to do this, as well - just name the input field with the name of the taxonomy you want to use.
234
-
235
- It's also possible to do a dropdown for custom taxonomies, using the same function. Just adjust the arguments like this:
236
-
237
- `wp_dropdown_categories(array('show_option_all' => 'All people', 'name' => 'people', 'taxonomy' => 'people'));`
238
-
239
- This would do a dropdown box for the "People" taxonomy. The 'name' must be the keyword used in the URL, while 'taxonomy' has the name of the taxonomy.
240
-
241
- = Automatic indexing =
242
- Relevanssi indexes changes in documents as soon as they happen. However, changes in shortcoded content won't be registered automatically. If you use lots of shortcodes and dynamic content, you may want to add extra indexing. Here's how to do it:
243
-
244
- `if (!wp_next_scheduled('relevanssi_build_index')) {
245
- wp_schedule_event( time(), 'daily', 'relevanssi_build_index' );
246
- }`
247
-
248
- Add the code above in your theme functions.php file so it gets executed. This will cause WordPress to build the index once a day. This is an untested and unsupported feature that may cause trouble and corrupt index if your database is large, so use at your own risk. This was presented at [forum](http://wordpress.org/support/topic/plugin-relevanssi-a-better-search-relevanssi-chron-indexing?replies=2).
249
-
250
- = Highlighting terms =
251
- Relevanssi search term highlighting can be used outside search results. You can access the search term highlighting function directly. This can be used for example to highlight search terms in structured search result data that comes from custom fields and isn't normally highlighted by Relevanssi.
252
-
253
- Just pass the content you want highlighted through `relevanssi_highlight_terms()` function. The content to highlight is the first parameter, the search query the second. The content with highlights is then returned by the function. Use it like this:
254
-
255
- `if (function_exists('relevanssi_highlight_terms')) {
256
- echo relevanssi_highlight_terms($content, get_search_query());
257
- }
258
- else { echo $content; }`

447
- * The excerpt-building algorithm is completely rewritten based on work by Ben Boyter (http://www.boyter.org/).

- = 3.4.1 =
460
- * Removed a notice about an undefined variable.
461
-
462
- = 3.4 =
463
- * New filter: `relevanssi_valid_admin_status` can be used to adjust post statuses that Relevanssi will handle.
464
- * If Relevanssi creates an empty excerpt for a post and there's a user-set excerpt for the post, that excerpt is used.
465
- * No ellipsis is added to the post excerpt, if the post excerpt shows the whole post.
466
- * The `relevanssi_post_title_before_tokenize` filter now has a second parameter that contains the post object.
467
- * New filter: `relevanssi_display_common_words` can be used to disable the "25 most common words" listing on the settings page, if it's too heavy to load.
468
- * Relevanssi was sanitizing taxonomy titles too aggressively. That is now toned down a bit.
469
- * Relevanssi now supports `post_parent`, `post_parent__in` and `post_parent__not_in`, though you have to set them in `relevanssi_modify_wp_query` filter for them to work.
470
- * Meta query support should now be perfect; there were some limitations with complicated meta queries before.
471
-
472
- = 3.3.8 =
473
- * Fixed a bug that caused the results to change depending of the order of words in a multi-word search query.
474
- * Added `product_categories` and `recent_products` from WooCommerce to the list of blocked shortcodes.
475
- * There are improvements in excerpt-building and highlighting, especially when fuzzy search is enabled.
476
- * Fixed a possible (if quite unlikely) XSS vulnerability.
477
- * Improved search performance (thanks to MikeNGarrett).
478
- * Sometimes highlights in documents make the document content disappear. I don't know why, but I've added a fix that should make the content visible (without the highlights) if a problem appears.
479
-
480
- = 3.3.7.1 =
481
- * Fixed bbPress compatibility.
482

484
- * Fixed bbPress compatibility.
485
-
486
- = 3.3.6 =
487
- * Relevanssi handles taxonomy terms in search better. The change requires a reindexing.
488
- * Fix in indexing: Relevanssi will now bypass the global $post when indexing. This should help with problems with the Cookie Law Info plugin, for example.
489
- * Tax query relation setting didn't work properly. It is now fixed.
490
- * Word-based excerpt building sometimes created too short excerpts. That is now fixed.
491
- * Synonyms are now highlighted.
492
- * Phrase matching had issues where searching for a too common phrase crashed the search. That has been fixed.
493
- * LIKE operator didn't work properly in meta_queries.
494
- * Problems with Avatar Upload plugin are fixed.
495
- * Offset errors with mb_stripos() shouldn't happen anymore.

499
- * New filter: `relevanssi_order` lets you modify the $order value before Relevanssi sorts posts.
500

- * Deprecated use of `like_escape` has been fixed.
503
-
504
- = 3.3.5 =
505
- * Fixed a bug where excluding posts would cause the search to fail.
506
- * Fixed a bug causing duplicate search results in WPML searches.
507
- * Increased plugin safety against hackers.
508
- * There was a bug in `relevanssi_comment_content_to_index` filter.
509
- * Some people had problems with the log entry timestamps. Fixed that.
510
- * New filter: `relevanssi_prevent_default_request` gives you more control over where Relevanssi prevents the default query from running.
511
- * New filter: `relevanssi_private_cap` lets you set the correct capability for finding private posts in custom post types.
512
- * The option to exclude categories and tags from search only worked for categories, not tags. Tags have been separated to a different option.
513
-
514
- = 3.3.4 =
515
- * Couple of bug fixes.
516
-
517
- = 3.3.3 =
518
- * OR fallback had problems.
519
- * Indexing sub pages didn't work.
520
- * Relevanssi now automatically treats 'ß' as 'ss'. If your site has 'ß' in text, reindexing the database is a good idea.
521
- * Query variable `post_status` is now supported.
522
-
523
- = 3.3.2 =
524
- * Fixed a warning on search results page.
525
-
526
- = 3.3.1 =
527
- * Fixed bugs related to the removal of the cache feature.
528
-
529
- = 3.3 =
530
- * Improvements to excerpts: excerpts with phrases work much better now, and the excerpt creation logic has been improved: the excerpts are now better. The process takes a bit more time, though.
531
- * Allowing HTML tags in excerpts could lead to those tags being left open. Relevanssi will now try to close open HTML tags in excerpts.
532
- * Allowed tags were not controlled in comments. They are now.
533
- * Highlighting in documents didn't always work; it should be more reliable now.
534

539
- * Errors about $wpdb->prepare() missing an argument removed.
540
- * New functions: `relevanssi_the_title()` and `relevanssi_get_the_title()` can be used to display highlighted titles in search results.
541
- * The old title highlighting method has been disabled, because it caused highlights in wrong places. Now the highlighted title is stored in $post->highlighted_post_title, take it from there or use the Relevanssi title functions to display it.
542
- * Polylang and WPML support was adjusted to perform better in edge cases.
543
- * Indexing is faster, thanks to some improved code from Tom Novelli.
544
- * MySQL injection attack vulnerability removed.
545
- * The cache feature is now removed. Relevanssi should automatically drop the cache tables.
546

547
-
548
- = 3.2 =
549

550
- * Titles are put through the_title filter before indexing.
551
- * New filter: `relevanssi_join` can be used to join tables in the Relevanssi search MySQL queries. Thanks to Ninos Ego.
552
- * New filter: `relevanssi_post_content` can be used to modify post content before any Relevanssi processing.
553
- * New filter: `relevanssi_post_content_before_tokenize` can be used to modify post content just before it's tokenized.
554
- * New filter: `relevanssi_indexing_values` can be used to modify what Relevanssi stores in the index.
555
- * New filter: `relevanssi_default_meta_query_relation` can be used to change the default meta query relation (default value is "AND").
556
- * When using a meta_query, `relation` can be set to OR now.
557
- * Phrases are now matched to excerpts.
558
- * Number of queries Relevanssi generates is much, much lower.
559

560
- * Better set of Russian stopwords.
561

562
-
563

- * Fix to make Relevanssi compatible with WordPress 3.7.
565
- * Fixed a mistyped database table name.
566
- * Relevanssi disables responsive-flipbook shortcode in indexing; it was causing problems.
567
- * Fixed a problem with an author dropdown with no author selected.
568
-
569
- = 3.1.8 =
570
- * Category restriction and exclusion and couple of other category-related settings didn't work properly.
571
- * Support for Polylang broke the support for WPML. That is now fixed.
572
- * One deprecated `$wpdb->escape()` was still left; it's gone now.
573
- * Shortcode `layerslider` was causing problems with Relevanssi; Relevanssi now disables it before building excerpts.
574
- * Relevanssi won't break BBPress search anymore.
575
- * If Relevanssi Premium is installed, deleting Relevanssi will not remove the databases and the options.
576
-
577
- = 3.1.7 =
578
- * New filter: `relevanssi_comment_content_to_index` lets you modify comment content before it's indexed by Relevanssi (to index comment meta, for example).
579
- * Facetious support: if post_type is set to -1, Relevanssi will not hang up on it.
580
- * Numerical search terms work better now.
581
- * Excerpt-building had issues, which are now fixed.
582
- * Punctuation removal now replaces &nbsp; with a space.
583
- * "starrater" short code from GD Star Rating is now disabled in indexing.
584
- * Punctuation removal now replaces invisible spaces with a normal space.
585
- * Division by zero error caused by 0 in posts_per_page is now prevented, and -1 value for posts_per_page handled better.
586
- * Relevanssi doesn't apply `get_the_excerpt` filters to excerpts it builds any more.
587
- * New filter: `relevanssi_excerpt` lets you modify the excerpts Relevanssi creates.
588
- * Relevanssi now suspends WP post cache while indexing, making indexing a lot more efficient. Thanks to Julien Mession for this one.
589
- * Deprecated function errors in 3.6 removed.
590
- * When search included user profiles or taxonomy terms, Relevanssi would generate lots of MySQL errors. Not anymore.
591
- * New filter: `relevanssi_valid_status` lets you modify the post statuses Relevanssi indexes.
592
- * New filter: `relevanssi_index_taxonomies_args` lets you modify the arguments passed to get_terms() when indexing taxonomies (for example to set 'hide_empty' to false).
593
- * Searching by taxonomy ID could confuse two taxonomies with the same term_id. The search is now checking the taxonomy as well to see it's correct.
594
- * Basic support for Polylang plugin.
595
- * Russian and Italian stopwords are now included, thanks to Flector and Valerio Vendrame.
596
- * Small fix in the way user meta fields are handled.
597
-
598
- = 3.1.6 =
599
- * DEACTIVATE AND ACTIVATE THE PLUGIN AFTER YOU UPDATE.
600
- * Fuzzy searches are now a lot more efficient; they were a huge resource hog before.
601
- * Fixed a possible MySQL injection attack.
602
- * Fixed MySQL errors from empty meta queries.
603
- * Sort order (orderby and order variables) are now read from query variables instead of global variables.
604
- * Relevanssi will not choke on bad values of orderby anymore.
605
- * Limit searches is improved: when using AND search it is less likely to miss results.
606
- * Phrase recognition read the whole post content (which it didn't need) from database, causing memory issues in some cases. Fixed that.
607
- * Highlighting was broken, and should work much better now.
608
-
609
- = 3.1.5 =
610
- * OR fallback didn't actually fall back to OR, but instead got stuck in an endless loop of AND searches.
611
- * Meta queries didn't work without a key; now they work with just meta_value or meta_value_num.
612
- * Meta queries had problems with meta_value being set to null.
613
- * Relevanssi now supports category__and. By default this sets include_children to false.
614
- * When querying by slug, the term taxonomy is also taken into consideration, fixing problems when same slug appears in different taxonomies.
615
- * Author search didn't work.
616
- * Fixed an error message caused by all-number synonyms starting with zero, like 02.
617
- * Synonyms are now case-insensitive.
618
- * New filter: `relevanssi_default_tax_query_relation` can be used to change the default tax query relation from OR to AND.
619
- * Fixed undefined variable errors when doing an OR fallback.
620
- * New filter: `relevanssi_bots_to_not_log` makes it possible to block bots from logs. The format matches what other plugins, ie. WP-Useronline, use for bot blocking, so you can share block lists.
621
- * New filter: `relevanssi_admin_search_ok` gives you more control when Relevanssi overrides the default WP search in admin, useful for fixing P2P_Box AJAX search.
622
- * Ordering search results by title or date in admin search works now.
623
- * Modified the way the highlights work; now highlighting words with apostrophes should produce more meaningful results.
624
- * Highlighting should not highlight anything between & and ; or in <style> or <script> tags, thus solving some of the problems related to highlights. Reports of how well this works are welcome.
625
- * On-post highlighting now only highlights content in the loop, so menu texts and other off-the-loop stuff should not get highlights anymore.
626
- * New action hook: `relevanssi_pre_indexing_query` can be used to "SET OPTION SQL_BIG_SELECTS=1" if needed.
627
- * Major indexing problems caused by shortcodes changing the post ID during the indexing of posts are now fixed.
628
- * Relevanssi was being called twice when a post was saved, on `save_post` and `wp_insert_post`. I removed the hook on `save_post`.
629
- * Unsuccessful searches are now ordered by count, like the successful queries are.
630
-
631
- = 3.1.4 =
632
- * Choosing which taxonomies to index is now done with an easy-to-use checkbox list.
633
- * Support for WP Table Reloaded and TablePress. Tables created with these plugins will now be expanded and the content indexed by Relevanssi.
634
- * New filter: `relevanssi_index_comments_exclude` can be used to exclude comments from indexing. The filter gets the post ID as a parameter, so you can prevent comments of particular posts being indexed, yet index those posts.
635
- * Relevanssi now adds spaces between tags when creating excerpts to make neater excerpts from tables and other similar situations.
636
- * Relevanssi now indexes unattached attachments, if you choose to index attachments.
637
- * Fixed the problems with Twenty Ten and Twenty Eleven themes better.
638
- * $match->tag now contains the number of tag hits.
639
- * Relevanssi now adds relevance score to posts before passing them to relevanssi_hits_filter. You can find it in $post->relevance_score.
640
- * Tags in breakdowns always showed 0, even though tags were indexed and searched correctly. That's now fixed.
641
-
642
- = 3.1.3 =
643
- * AND search did not work in all cases.
644
- * Posts couldn't be found by category name. Fixed that.
645
-
646
- = 3.1.2 =
647
- * Exclude category option was broken. Fixed that.
648
- * Searching for a non-existing category ID caused an error. Fixed that.
649
- * Occasional blank screens of death occurred when multibyte string operations weren't installed. That should not happen anymore.
650
- * Fallback to OR search was a bit broken.
651
-
652
- = 3.1.1 =
653
- * Small fix to prevent database errors.
654
- * Small fix to prevent disappearing excerpts.
655
-
656
- = 3.1 =
657
- * Fixed the uninstalling instructions.
658
- * Fixes a problem with Twenty Ten and Twenty Eleven themes that caused doubled "Continue Reading" links.
659
- * Fixed a notice about undefined variable on plugin update pages.
660
- * Small bug fixes on search to remove warning notices.
661
- * New filter: `relevanssi_index_custom_fields` can be used to modify the list of custom fields to index.
662
- * Deleting menus caused a warning. That is now fixed.
663
- * Relevanssi has an option to disable IP logging (which is actually illegal in some countries). Thanks to Stefan Eufinger.
664
- * Searching in subcategories worked sometimes, but not always. Thanks to Faebu.
665
- * The "Limit searches" option didn't work too well in the case of strong weightings, as it didn't take note of any weights. Now it works better.
666
- * Added a note about disabling custom excerpts when they are not needed - they can slow down the search quite a bit.
667
- * New filter: `relevanssi_options_capability` can be used to modify the capability required to see the options page (default is `manage_options`).
668
- * Fixed the way IDF is calculated to account some extreme cases with small databases.
669
- * New filter: `relevanssi_index_custom_fields` gives added control over which custom fields are indexed.
670
- * Fixed filter: `relevanssi_pre_excerpt_content` wasn't working properly.
671
- * Relevanssi now supports tax_query, for most part. You can query multiple taxonomies, use relation AND and OR, use operators AND, IN and NOT IN and choose include_children (which defaults to true). Old `taxonomy` and `term` still work, but I recommend using tax_query for the level of control it offers.
672
- * Relevanssi now works better with category restrictions. The extra `cats` query variable is no longer necessary, Relevanssi can now read multiple categories from `cat`. You can also use `category__and`, `category__in` and `category__not_in`.
673
- * Same goes with tags: `tags` is now longer necessary. Relevanssi has full support for `tag`, `tag_id`, `tag__and`, `tag__in`, `tag__not_in`, `tag_slug__and`, `tag_slug__in` and `tag_slug__not_in`. For `tag`, both `term1+term2` and `term1,term2` is supported.
674
- * Relevanssi now supports `author_name` and negative values for `author`.
675
- * Relevanssi now supports `offset` query variable.
676
- * Relevanssi now supports meta_query. You can use all comparisons (also EXISTS and NOT EXISTS, even if you don't have WP 3.5). You can also use the older `meta_key` and `meta_value` query variables, including all the comparisons. I have not tested all possible meta_query constructions, so bug reports of things that don't work as expected are welcome.
677
- * New index on the database makes some database operations faster.
678
- * Removed a bug that prevents one-character words from being indexed in titles, despite the minimum word length setting.
679
- * Removed a warning when searching for nothing.
680
- * Fixes a warning about $wpdb->prepare() caused by a change in WordPress 3.5.

684
- * Fixed a major bug that caused the searches to fail when "Limit searches" was enabled, but "Limit" was not defined.
685
- * Modified `relevanssi_remove_punct()` to replace curly apostrophes and quotes with spaces instead of removing them, to make the index more consistent (regular apostrophes were replaced with spaces). Reindexing the database is a good idea.
686
- * Fixed some misleading text on the options page.
687
-
688
- = 3.0.4 =
689
- * AFTER UPGRADING FROM 2.x: Make sure you deactivate and reactivate Relevanssi in order to make the database changes happen.

699
-
700
- = 3.0.2 =
701
- * AFTER UPGRADING FROM 2.x: Make sure you deactivate and reactivate Relevanssi in order to make the database changes happen.
702
- * Fixed the "Cannot use a scalar value as an array" bug in indexing.
703
- * Role-Scoper users: in order to make Relevanssi work with Role-Scoper, replace the Relevanssi helper file in Role-Scoper with [this file](https://www.relevanssi.com/relevanssi-helper-front_rs.txt).
704
- * Removed an error message about set_time_limit() under safe_mode.
705
- * Jetpack Contact Form shortcode caused problems when indexing. Relevanssi will now simply remove the shortcode before indexing.
706
- * Fixed errors caused by / characters in highlighting.
707

- = 3.0.1 =
709
- * AFTER UPGRADING FROM 2.x: Make sure you deactivate and reactivate Relevanssi in order to make the database changes happen.
710
- * Fixed lots of problems in logging searches.
711
- * Added an alert when user hasn't selected any post types to index (and default values).
712
- * Custom field setting 'visible' works now.
713
- * Searching by category title works now, and you can adjust the category weight in the settings.
714
-
715
- = 3.0 =
716
- * AFTER UPGRADING FROM 2.x: Make sure you deactivate and reactivate Relevanssi in order to make the database changes happen.
717
- * WORD OF WARNING: This is a major update, with lots of changes as you can see, and since I couldn't find any beta testers to help test it out, consider this a beta release, with bugs probable.
718
- * The database has been updated to match the more advanced structure in Relevanssi Premium. This requires a re-indexing of the database.
719
- * The indexing process is more efficient now.
720
- * Relevanssi now includes a throttle feature, which makes the searches more efficient.
721
- * Relevanssi now disables the default WP search.
722
- * The custom field search hack using `cat` set to "custom" doesn't work any more. If you wish to filter by custom field, you need Relevanssi Premium, which does it better anyway.
723
- * Relevanssi can handle certain whitespace characters better in indexing.
724
- * Apostrophes are now replaced with whitespace instead of being removed.
725
- * Relevanssi now shows correct number of results when posts_per_page is set to -1.
726

731
- * Relevanssi now updates index for posts added with wp_update_post() function. (Thanks to Simon Blackbourn)
732

733
- * Fixed warnings for undefined variables.
734
- * Relevanssi won't mess media library searches any more.
735
- * Search terms are no longer highlighted in titles on post pages. That caused too many problems.
736
- * New collation rules to MySQL databases will make sure that word pairs like "pode" and "pôde" will not be considered duplicates in the stopword database.
737
- * You can now set the "Custom fields to index" to "all" to index all custom fields and "visible" to index all visible custom fields (but not the ones with names starting with an underscore).
738
- * Plugin now works properly without multibyte string functions.
739

740
- * New filter: `relevanssi_modify_wp_query` lets you modify $wp_query before it is passed to Relevanssi.
741

744
- * New filter: `relevanssi_ellipsis` lets you change the default '...' in excerpts to something else.
745
- * New filter: `relevanssi_do_not_index` is given a post ID and expects a boolean in return: should this post be indexed or not?
746
- * New filter: `relevanssi_match` lets you meddle with the matching engine.
747
- * New filter: `relevanssi_results` filters the result set from the search.
748
- * New filter: `relevanssi_content_to_index` let's you add whatever content you wish to posts before they are indexed.
749
- * New filter: `relevanssi_didyoumean_query` let's you modify the query for Did you mean? queries
750
- * Changed filter: `relevanssi_post_ok` has different arguments, see source code for details.
751
- * New shortcode: use shortcode `noindex` to wrap parts of posts you want to keep from the index.
752
- * And a bunch of other changes.

-
934
- = 2.4 =
935
- * Highlighting post content won't highlight inside HTML tags anymore.
936

966
-
967

969
-
970

972

973
- * Phrases are now matched also in post titles and category titles (before they were only matched against post content).
974

975
- * Set the constant TIMER to true to enable timing of the search process for debugging reasons.
976
-
977
- = 2.1.6 =

991
- * OR operator makes a comeback! The default operator is now an option, and if you choose AND and search gets no results, an OR search is also run.
992

993
-
994

1015

1045
-
1046

1047

1048
-
1049

+ Do note that using Relevanssi may require large amounts (hundreds of megabytes) of database space. If your hosting setup has a limited amount of space for database tables, using Relevanssi may cause problems. In those cases use of Relevanssi cannot be recommended.
21
 
22

  * Search results sorted in the order of relevance, not by date.
36

37
  * Index the contents of shortcodes.
38
  * Google-style "Did you mean?" suggestions based on successful user searches.

  == Screenshots ==

71
 
72
  == Installation ==
73
 
74
+ 1. Install the plugin from the WordPress plugin screen.
75
+ 1. Activate the plugin.
76
+ 1. Go to the plugin settings page and build the index following the instructions there.
77
+ 1. That's it!
78
 
79
+ Relevanssi uses the standard search form and doesn't usually need any changes in the search results template.
 
 
 
 
 
 
80
 
81
  If the search does not bring any results, your theme probably has a query_posts() call in the search results template. That throws Relevanssi off. For more information, see [The most important Relevanssi debugging trick](https://www.relevanssi.com/knowledge-base/query_posts/).
82
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
83
  = Uninstalling =
84
  To uninstall the plugin remove the plugin using the normal WordPress plugin management tools (from the Plugins page, first Deactivate, then Delete). If you remove the plugin files manually, the database tables and options will remain.
85
 
 
 
 
 
 
86
  == Frequently Asked Questions ==
87
 
88
  = Knowledge Base =
89
  You can find solutions and answers at the [Relevanssi Knowledge Base](https://www.relevanssi.com/category/knowledge-base/).
90
 
91
+ = Contextual help =
92
+ Answers to many common problems can be found from the contextual menu. Just click "Help" in the top right corner of your WordPress admin dashboard on the Relevanssi settings page.
93
+
94
  = Relevanssi doesn't work =
95
+ If you the results don't change after installing and activating Relevanssi, the most likely reason is that you have a call to `query_posts()` on your search results template. This confuses Relevanssi. Try removing the `query_posts()` call and see what happens.
96
 
97
  = Searching for words with ampersands or hyphens doesn't work =
98
+ Please read [Words with punctuation can't be found](https://www.relevanssi.com/knowledge-base/words-ampersands-cant-found/). This is a Relevanssi feature, but you can fix it from Relevanssi indexing settings.
99
 
100
  = Where are the user search logs? =
101
+ See the top of the admin menu. There's 'User searches'.
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
102
 
103
  = Displaying the relevance score =
104
  Relevanssi stores the relevance score it uses to sort results in the $post variable. Just add something like
108
  to your search results template inside a PHP code block to display the relevance score.
109
 
110
  = Did you mean? suggestions =
111
+ Relevanssi offers Google-style "Did you mean?" suggestions. See ["Did you mean" suggestions](https://www.relevanssi.com/knowledge-base/did-you-mean-suggestions/) in the Knowledge Base for more details.

  = What is tf * idf weighing? =
114
 
120
 
121
  Each document database is full of useless words. All the little words that appear in just about every document are completely useless for information retrieval purposes. Basically, their inverted document frequency is really low, so they never have much power in matching. Also, removing those words helps to make the index smaller and searching faster.
122
 
 
 
 
 
123
  == Thanks ==
124
  * Cristian Damm for tag indexing, comment indexing, post/page exclusion and general helpfulness.
125
  * Marcus Dalgren for UTF-8 fixing.
129
 
130
  == Changelog ==
131
 
132
+ = 4.0.5 =
133
+ * Relevanssi code has been reviewed and modified to follow WordPress coding standards. As a result, there have been minor improvements all around the code to make things more robust and secure.
134
+ * Custom field detail is no longer serialized. It's now JSON. If you use custom field detail, rebuild the index and change your code to use json_decode() instead of unserialize().
135
+ * `relevanssi_the_tags()` and `relevanssi_get_the_tags()` now have different set of parameters, more in line with `the_tags()` and `get_the_tags()`.
136
+ * Taxonomy indexing settings were emptied out if you saved another options tab. That is now fixed.
137
+ * Improvements to WPML support; WPML is now less likely to be confused in multisite searches.
138
+ * Updated filter: `relevanssi_search_ok` now gets the WP_Query object as a parameter, which is helpful if you're not using the global $wp_query.
139
+ * ACF Flexible Content field indexing didn't work properly, possibly due to a change in ACF. That should now work better.
