Relevanssi – A Better Search


Relevanssi remplace la recherche standard de WordPress par un meilleur moteur de recherche avec beaucoup de fonctionnalités et d’options configurables. Vous obtenez de meilleurs résultats, une meilleure présentation des résultats – vos utilisateurs vous remercieront.

This is the free version of Relevanssi. There’s also Relevanssi Premium, which has added features. For more information about Premium, see

Do note that using Relevanssi may require large amounts (hundreds of megabytes) of database space (for a reasonable estimate, multiply the size of your wp_posts database table by three). 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.

  1. Installer l’extension depuis la page Extensions de WordPress.
  2. Activer l’extension.
  3. Go to the plugin settings page and build the index following the instructions there.
  4. C’est tout !

Relevanssi uses the standard search form and doesn’t usually need any changes in the search results template.

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.


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.


Base de connaissances

You can find solutions and answers at the Relevanssi Knowledge Base.

Contextual help

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.

Relevanssi ne fonctionne pas

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.

Searching for words with ampersands or hyphens doesn’t work

Please read Words with punctuation can’t be found. This is a Relevanssi feature, but you can fix it from Relevanssi indexing settings.

Où sont les logs de recherche de l’utilisateur ?

See the top of the admin menu. There’s ‘User searches’.

Displaying the relevance score

Relevanssi stores the relevance score it uses to sort results in the $post variable. Just add something like

echo $post->relevance_score

to your search results template inside a PHP code block to display the relevance score.

Did you mean? suggestions

Relevanssi offers Google-style « Did you mean? » suggestions. See « Did you mean » suggestions in the Knowledge Base for more details.

What is tf * idf weighing?

It’s the basic weighing scheme used in information retrieval. Tf stands for term frequency while idf is inverted document frequency. Term frequency is simply the number of times the term appears in a document, while document frequency is the number of documents in the database where the term appears.

Ainsi, le poids du mot dans un document augmente plus il apparaît dans ce document et moins il apparaît dans les autres documents.

What are stop words?

Chaque document est composé de plein de mots inutiles. Tous ces petits mots qui apparaissent dans à peu près tous les documents sont inutiles pour retrouver une information. En outre, leur poids dans la recherche de correspondance est très faible. De plus, retirer ces mots contribue à réduire la taille de l’index et accélère la recherche.


Recommend this to friends

Using the free version. It works well with Divi. Am not as tech-savvy as I would like, and so asked a help desk question and got a quick, helpful reply.

Increases clicks from search pages

I've been using this plugin for years and it definitely increases the # of clicks from my search pages. Relevance, not date, should trump and I appreciate the time put into the settings, that it doesn't create a new tab in WordPress, and how well it just works.

Search Box Never found

All of the features seem to work as advertised. However, there is no mention of actually how to do a search. As in where do I type in the search item? And I never found it. Finally gave up.

Great UX => Findability

The way Relevanssi enables findability within a site is the most powerful component you can add to a user's search experience. Synonyms and the ability to look intelligently within custom types and fields (to name a few) just opens up the content in a way that native search does not. This allows us, for example, to easily add words in a custom post field that is reflective of a user's natural language — an important consideration for e-commerce and directory sites. Search is a powerful navigational tool in itself and crafting its construct is part of the "invisible" care and attention that we can put into our products to provide exceptional and relevant experiences (for both our clients, and their customers). Relevanssi helps us control this relevance in balance with a client's business decision to never give a user a dead-end of no results. No results are bad, but irrelevant results can be worse. The unexpected, swift and selfless support form the author, Mikko, was also a life saver on our last project when we needed that extra bit of genius to make the project great with a very specific query.

Excellent plugin

It does all I need and more! Support is great, the knowledge base is also very helpful providing quick solutions for most of my problems. Plugin is lightweight and easy to configure. Tested with large databases, indexing over 10,000 pages with no problem.

  • EXISTS and NOT EXISTS didn’t work for taxonomy terms in searches.
  • WPML post type handling has been improved. If post type allows fallback for default language, Relevanssi will support that.
  • Relevanssi now reminds you to set up automatic trimming for the logs. It’s a really good idea, otherwise the logs will become bloated, which will hurt search performance.
  • The Groups posts filter is only applied to public posts to avoid drafts being shown to people who shouldn’t see them.
  • The posts_per_page query variable didn’t work; it’s now added to the introduced query variables so that it works.
  • Relevanssi won’t log empty queries anymore.
  • The default tax query relation was switched from OR to AND to match the WP_Query default behaviour.
  • When used with WP 5.1, Relevanssi will now use wp_insert_site instead of the now-deprecated wpmu_new_blog.
  • Multisite blog creation is handled better in WP 5.1+.
  • Relevanssi now supports Restrict Content Pro permissions.


  • Improvements to meta key sorting.
  • Relevanssi settings page won’t let you exclude categories you have restricted the search to.
  • Members plugin compatibility has been improved: it’s only used if the ‘content permissions’ feature has been enabled.
  • The excerpt settings page was a bit buggy.
  • Slimstat analytics is now added to the blocked shortcodes list.
  • New filter: relevanssi_search_form works exactly like get_search_form, but only applies to the Relevanssi shortcode search forms.
  • New JetPack taxonomies and post types have been added to the block list so they won’t appear in Relevanssi settings.


  • Choosing « CSS Style » for highlighting was not possible. That is now fixed.
  • Gutenberg reusable block indexing was fatally broken with the latest Gutenberg version. That has been updated.
  • Relevanssi now by default respects the WooCommerce « exclude from search » setting.
  • post__not_in still didn’t work properly, it does now.
  • New filter: relevanssi_comparison_order can be used to define the sorting order when sorting the results by post type.
  • « Did you mean » process included a very slow query. It is now cached, leading in some cases to massive performance improvements (we’re talking about several seconds here).
  • Highlights inside code and similar blocks are handled better now.

  • Fixes the broken User searches page.

  • Adding the missing Gutenberg compatibility file.


  • Relevanssi can now index Gutenberg reusable blocks. (This functionality broke once already before release, so that can happen, since Gutenberg is still in very active development.)
  • The post__in and post__not_in parameters didn’t work, and are now fixed. post_parent__in and post_parent__not_in are also improved.
  • You can use named meta queries for sorting posts. Meta query sorting is improved in other ways as well.
  • Log export didn’t work properly.
  • Adding stopwords from the common word list has been fixed.
  • The relevanssi_get_words_having filter hook is now also applied to the free version Did you mean queries.
  • New filters: relevanssi_1day and relevanssi_7days can be used to adjust the number of days for log displays, so instead of 1, 7 and 30 days you can have anything you want.

  • Actually working admin search.


  • New feature: You can now export the search log as a CSV file.
  • New feature: Admin Search page allows you to perform searches in WP admin using Relevanssi.
  • New filter: relevanssi_admin_search_capability can be used to adjust who sees the admin search page.
  • New filter: relevanssi_entities_inside_pre and relevanssi_entities_inside_code adjust how HTML entities are handled inside pre and code tags.
  • Numeric meta values (meta_value_num) are now sorted as numbers and not strings.
  • Pinned posts have $post->relevanssi_pinned set to 1 for debugging purposes, but you can also use this for styling the posts in the search results templates.
  • The Did you mean feature has been toned down a bit, to make the suggestions slightly less weird in some cases.
  • Post parent parameters now accept 0 as a value, making it easier to search for children of any post or posts without a parent.
  • Polylang compatibility has been improved.
  • Phrases with apostrophes inside work better.
  • The relevanssi_excerpt filter hook got a second parameter that holds the post ID.
  • Custom field sorting actually works now.
  • WP Search Suggest compatibility added.
