Relevanssi – A Better Search

Description

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 Relevanssi.com.

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.

Installation

  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.

Désinstallation

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.

FAQ

Base de connaissances

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

Aide contextuelle

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 journaux 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.

Avis

This plugin worked in all ways for me (front end, back end, custom post types, custom taxonomies). It's just awesome. And the support is the best I've ever seen.

I rarely find a plugin that does exactly what I need, clearly and efficiently (therefore, I usually build it myself). The various but smooth settings allow a perfect fine tuning: nothing more and nothing less than what is really needed. My compliments!
26 juillet 2022
Great searching engine that works without needing a lot of work - altough you can set everything to your liking if you want. The support is fast and responsive if you have a problem. Even if it's your own fault 😉

I cannot understand why Relevanssi does not have more active installs, since the years it's the best plugin to sort the WP search results by Relevancy. I would like to see 1 million installs soon, it deserves.

Journal

4.17.1

  • Minor fix: WooCommerce layered navigation compatibility caused enough problems that I’ve disabled it by default. You can enable it with add_filter( 'woocommerce_get_filtered_term_product_counts_query', 'relevanssi_filtered_term_product_counts_query' );.
  • Minor fix: Data attribute handling for in-document highlighting is now better.

4.17.0

  • New feature: You can now look at how the posts appear in the database from the Debugging tab.
  • New feature: Relevanssi now works with WooCommerce layered navigation filters. The filter post counts should now match the Relevanssi search results.
  • New feature: New function relevanssi_count_term_occurrances() can be used to display how many times search terms appear in the database.
  • Changed behaviour: Relevanssi post update trigger is now on wp_after_insert_post instead of wp_insert_post. This makes the indexing more reliable and better compatible with other plugins.
  • Changed behaviour: Previously, throttling searches has been impossible when results are sorted by date. Now if you set Relevanssi to sort by post date from the searching settings, you can enable the throttle and the throttling will make sure to keep the most recent posts. This does not work if you set the orderby to post_date elsewhere.
  • Minor fix: Prevents Relevanssi from interfering in fringe cases (including The Event Calendar event search).
  • Minor fix: Relevanssi added the highlight parameter to home page URLs, even though it shouldn’t.
  • Minor fix: Indexing nav_menu_item posts is stopped earlier in the process to avoid problems with big menus.
  • Minor fix: If the sentence query variable is used to enable phrase searching, Relevanssi now adds quotes to the highlight parameter.
  • Minor fix: Add support for JetSmartFilters.
  • Minor fix: Add support for WooCommerce products attribute lookup table filtering.
  • Minor fix: Improve excerpts to avoid breaking HTML tags when tags are allowed.
  • Minor fix: Fix broken tag and category weight settings.
  • Minor fix: Improve Polylang language detection.
  • Minor fix: Relevanssi now hyphenates long search terms in the User searches page. This prevents long search terms from messing up the display.
  • Minor fix: Improve WPFD file content indexing support. Relevanssi indexing now happens after the WPFD indexing is done.
  • Minor fix: Add support for TablePress table_filter shortcodes.
  • Minor fix: Stopped some problems with Did you mean suggestions suggesting the same word if a hyphen was included.
  • Minor fix: Paging didn’t work in admin searches for hierarchical post types (like pages).
  • Minor fix: In-document highlighting could break certain elements thanks to Relevanssi messing up data attributes.
  • Minor fix: Relevanssi now recursively runs relevanssi_block_to_render and the CSS relevanssi_noindex filtering for inner blocks.

4.16.0

  • New feature: Oxygen compatibility has been upgraded to support JSON data from Oxygen 4. This is still in early stages, so feedback from Oxygen users is welcome.
  • New feature: New filter hook relevanssi_oxygen_element is used to filter Oxygen JSON elements. The earlier relevanssi_oxygen_section_filters and relevanssi_oxygen_section_content filters are no longer used with Oxygen 4; this hook is the only way to filter Oxygen elements.
  • Changed behaviour: Relevanssi now applies remove_accents() to all strings. This is because default database collations do not care for accents and having accents may cause missing information in indexing. If you use a database collation that doesn’t ignore accents, make sure you disable this filter.
  • Minor fix: Relevanssi used the_category filter with too few parameters. The missing parameters have been added.
  • Minor fix: Stops drafts and pending posts from showing up in Relevanssi Live Ajax Searches.
  • Minor fix: Phrases weren’t used in some cases where a multiple-word phrase looked like a single-word phrase.
  • Minor fix: Prevents fatal errors from relevanssi_strip_all_tags().

4.15.2

  • New feature: New filter hook relevanssi_didyoumean_token lets you filter Did you mean words before correction. You can use this filter hook to exclude words from being corrected.
  • Minor fix: Phrase search couldn’t find phrases that include an ampersand if they matched the post title. This works now.
  • Minor fix: Relevanssi now adds spaces after table cell tags to avoid table cell content sticking together in excerpts.
  • Minor fix: The ‘Allowable tags in excerpts’ function now automatically corrects the entered value to match what Relevanssi expects the value to be.

4.15.1

  • Changed behaviour: Relevanssi now ignores WordPress metadata custom fields that aren’t interesting for Relevanssi indexing.
  • Changed behaviour: Both relevanssi_get_permalink() and relevanssi_the_permalink() now can take post ID or a post object as a parameter and can thus be used outside the Loop.
  • Changed behaviour: The relevanssi_hits_filter hook now gets the WP_Query object as the second parameter.
  • Minor fix: Avoid error messages for missing mysqlcolumn_matches array key.

4.15.0

  • New feature: The action hook relevanssi_init runs at the end of the relevanssi_init() function.
  • New feature: New filter hook relevanssi_author_query_filter filters the post author MySQL query.
  • New feature: New filter hook relevanssi_by_date_query_filter filters the by_date MySQL query.
  • New feature: New filter hook relevanssi_date_query_filter filters the date query MySQL query.
  • New feature: New filter hook relevanssi_parent_query_filter filters the post parent MySQL query.
  • New feature: New filter hook relevanssi_post_query_filter filters the post__in and post__not_in MySQL query.
  • New feature: New filter hook relevanssi_post_status_query_filter filters the post_status MySQL query.
  • New feature: New filter hook relevanssi_post_type_query_filter filters the post_type MySQL query.
  • Minor fix: The Bricks compatibility was improved, Relevanssi now notices changes to Bricks posts more often. Relevanssi also only reads the text from the _bricks_page_content_2 custom field.
