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

3 octobre 2020
I tried more than 10 plugin, Nothing satisfied me except this.Hats-off to the developer
28 septembre 2020
I found Relevanssi looking for a tool that would allow my user to search document content, mainly PDFs. I installed the free version and was pleased everything worked perfectly, so I moved on to the Premium version. Now, I am running a few WordPress sites, and this was mainly for a multisite, so I was a little concerned about how it would work. I had some customization on the search results page that was causing some initial errors, but they were easy to work out. Later we had some specific requests that were outside of the plugins capabilities, specifically hiding PDFs or Doc until a post date so we could pre-build pages and test. I emailed Mikko asking if there were any options I could check in the settings for Relavenssi or something, and Mikko replied with a coding solution for my custom page that was perfect. He didn't have to give me development tips. He could have said, sorry that is not something available at this time. Mikko saved me days of trial and error, and I can not thank him enough. Mikko is outstanding, and I would highly recommend Relevanssi.

Journal

4.8.3

  • New feature: Both relevanssi_fuzzy_query and relevanssi_term_where now get the current search term as a parameter.
  • Minor fix: Relevanssi database tables don’t have PRIMARY keys, only UNIQUE keys. In case this is a problem (for example on Digital Ocean servers), deactivate and activate Relevanssi to fix the problem.
  • Minor fix: When posts_per_page was set to -1, the max_num_pages was incorrectly set to the number of posts found. It should, of course, be 1.
  • Minor fix: Excluding from logs didn’t work if user IDs had spaces between them (‘user_a, user_b’). This is now fixed for good, the earlier fix didn’t work.

4.8.2

  • New feature: New filter hook relevanssi_term_where lets you filter the term WHERE conditional for the search query.
  • Minor fix: Doing the document count updates asynchronously caused problems in some cases (eg. importing posts). Now the document count is only updated after a full indexing and once per week.
  • Minor fix: Phrase matching has been improved to make it possible to search for phrases that include characters like the ampersand.

4.8.1

  • Major fix: Changes in WooCommerce 4.4.0 broke the Relevanssi searches. This makes the WooCommerce search work again.
  • Minor fix: Excluding from logs didn’t work if user IDs had spaces between them (‘user_a, user_b’). Now the extra spaces don’t matter.
  • Minor fix: The asynchronous doc count action in the previous version could cause an infinite loop with the Snitch logger plugin. This is prevented now: the async action doesn’t run after indexing unless a post is actually indexed.
  • Minor fix: Relevanssi indexing procedure was triggered for autosaved drafts, causing possible problems with the asynchronous doc count action.
  • Minor fix: The relevanssi_index_custom_fields filter hook was not applied when doing phrase matching, thus phrases could not be found when they were in custom fields added with the filter.

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.
