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.

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.

Thus, the weight of the word for a document increases the more often it appears in the document and the less often it appears in other documents.

What are stop words?

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.

This is simply one of the best things that has happened to WordPress search-centric sites...keep it up

I use Relevanssi to make my search results come out exactly how I want them to. I have confidence that my users will be able to find the right content because of the powerful search and customizations that I can do with Relevanssi. I also recently posted in the support forum and heard back within one day with a fix to my problem. All this for a free plugin! Thank you Mikko.

This is a really nice plugin, and it is clear that a huge amount of work went into building it. Thank you, Mikko. It would be great if there could be an indexing option to index all posts modified after a certain date rather than having to index all posts.

I can't imagine any plugin having better support than Relevanssi. Outstanding plugin and developer. Mikko answers questions and offers solutions promptly and conscientiously -- beyond expectations. Thanks Mikko.

Journal

4.8.0

  • Changed behaviour: Relevanssi now requires PHP 7.
  • Changed behaviour: Relevanssi now sorts strings with strnatcasecmp() instead of strcasecmp(), leading to a more natural results with strings that include numbers.
  • Changed behaviour: Relevanssi init is now moved from priority 10 to priority 1 on the init hook to avoid problems with missing TablePress compatibility.
  • New feature: New filter hook relevanssi_get_approved_comments_args filters the arguments to get_approved_comments in comment indexing. This can be used to index custom comment types, for example.
  • New feature: Content wrapped in the noindex tags is no longer used for excerpts.
  • New feature: The [et_pb_fullwidth_code] shortcode is now removed completely, including the contents, when Relevanssi is indexing and building excerpts.
  • Major fix: Relevanssi didn’t index new comments when they were added; when a post was indexed or the whole index rebuilt, comment content was included. We don’t know how long this bug has existed, but it is now fixed. Rebuild the index to get all comment content included in the index.
  • Minor fix: Autoload has been disabled for several options that are not needed often.
  • Minor fix: Phrase matching did not work correctly in visible custom fields.
  • Minor fix: TablePress support could cause halting errors if posts were inserted before Relevanssi has loaded itself (on init priority 10). These errors will no longer happen.
  • Minor fix: The doc count update, which is a heavy task, is now moved to an asynchronous action to avoid slowing down the site for users.
  • Minor fix: Relevanssi only updates doc count on relevanssi_insert_edit() when the post is indexed.

4.7.2

  • Minor fix: Media Library searches failed if Relevanssi was enabled in the WP admin, but the attachment post type wasn’t indexed. Relevanssi will no longer block the default Media Library search in these cases.
  • Minor fix: Adds more backwards compatibility for the relevanssi_indexing_restriction change, there’s now an alert on indexing tab if there’s a problem.

4.7.1

  • New feature: New filter hook relevanssi_post_content_after_shortcodes filters the post content after shortcodes have been processed but before the HTML tags are stripped.
  • Minor fix: Adds more backwards compatibility for the relevanssi_indexing_restriction change.

4.7.0

  • New feature: New filter hook relevanssi_admin_search_blocked_post_types makes it easy to block Relevanssi from searching a specific post type in the admin dashboard. There’s built-in support for Reusable Content Blocks rc_blocks post type, for example.
  • New feature: The reason why a post is not indexed is now stored in the _relevanssi_noindex_reason custom field.
  • Changed behaviour: The relevanssi_indexing_restriction filter hook has a changed format. Instead of a string value, the filter now expects an array with the MySQL query in the index ‘mysql’ and a reason in string format in ‘reason’. There’s some temporary backwards compatibility for this.
  • Changed behaviour: Relevanssi now applies minimum word length when tokenizing search query terms.
  • Changed behaviour: Content stopwords are removed from the search queries when doing excerpts and highlights. When Relevanssi uses the untokenized search terms for excerpt-building, stopwords are removed from those words. This should lead to better excerpts.
  • Minor fix: Improves handling of emoji in indexing. If the database supports emoji, they are allowed, otherwise they are encoded.

4.6.0

  • Changed behaviour: Phrases in OR search are now less restrictive. A search for ‘foo « bar baz »‘ used to only return posts with the « bar baz » phrase, but now also posts with just the word ‘foo’ will be returned.
  • Minor fix: User Access Manager showed drafts in search results for all users. This is now fixed.
