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.

Ceci est la version gratuite de Relevanssi. Il existe aussi Relevanssi Premium avec des fonctionnalités en plus. Pour plus d’informations sur la version Premium, veuillez consulter Relevanssi.com.

Veuillez noter que Relevanssi peut nécessiter de grandes quantités (des centaines de mégaoctets) d’espace en base de données (pour une estimation raisonnable, multipliez la taille de votre table wp_posts par trois). Si votre configuration d’hébergement dispose d’un espace limité pour les tables de base de données, l’utilisation de Relevanssi peut causer des problèmes. Dans ce cas, il n’est pas recommandé de l’utiliser.

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.

Easy to install and configure, nstantly better and faster results, great docs and knowledge base. Love it.

At first I was sceptic because it just looked too good to be true. We bought the pro version for a client and we are thrilled. Also, we were unsure how to configure certain search settings (searching through ACF) so we contacted the support. They replied superfast and helpful. 10/10!

Been using this for over a year now. Been a fantastic plugin. Users love it. It's heavy, yes. But it is more efficient than other search plugins I've tried beyond going to the external service Elastic / Algolia route. Mikko is fantastic to deal with as well if you ever have any issues. Extremely easily to customize and works great with a lot of other plugins.

Since Relevanssi - take the first light of birth, i try to get that baby to run. I love the name of the Plug,(2Stars) but like parents you all time forget what bad things these plugins has done to you and your time with the webpage /blog.

Journal

4.18.3

  • New feature: New filter hook relevanssi_blocked_field_types can be used to control which ACF field types are excluded from the index. By default, this includes ‘repeater’, ‘flexible_content’, and ‘group’.
  • New feature: New filter hook relevanssi_acf_field_object can be used to filter the ACF field object before Relevanssi indexes it. Return false to have Relevanssi ignore the field type.
  • New feature: Relevanssi debug mode has more features now.
  • Minor fix: ACF field exclusion is now recursive. If a parent field is excluded, all sub fields will also be excluded.
  • Minor fix: Handling of data attributes in in-document highlighting had a bug that caused problems with third-party plugins.
  • Minor fix: The indexing settings tab now checks if the wp_relevanssi database table exists and will create the table if it doesn’t.

4.18.2

  • New feature: Relevanssi now has a debug mode that will help troubleshooting and support.
  • Minor fix: Using the_permalink() caused problems with search result links. That is now fixed. Relevanssi no longer hooks onto the_permalink hook and instead uses post_link and other similar hooks.

4.18.1

  • New feature: New filter hook relevanssi_add_highlight_and_tracking can be used to force Relevanssi to add the highlight and tracking parameters to permalinks.
  • Changed behaviour: The ‘relevanssi_wpml_filter’ filter function now runs on priority 9 instead of 10 to avoid problems with custom filters on relevanssi_hits_filter.
  • Minor fix: Handle cases of missing posts better; relevanssi_get_post() now returns a WP_Error if no post is found.
  • Minor fix: Search queries that contain apostrophes and quotes can now be deleted from the log.
  • Minor fix: Avoid a slow query on the searching tab when the throttle is not enabled.

4.18.0

  • New feature: Relevanssi now shows the MySQL max_allowed_packet size on the debug tab.
  • New feature: Relevanssi now shows the indexing query on the debug tab.
  • New feature: ACF field settings now include a ‘Exclude from Relevanssi index’ setting. You can use that to exclude ACF fields from the Relevanssi index.
  • Minor fix: Relevanssi was adding extra quotes around search terms in the highlight parameter.
  • Minor fix: Yet another update to data attributes in highlighting. Thanks to Faeddur.
  • Minor fix: Taxonomy query handling was improved. This should help in particular Polylang users who’ve had problems with Relevanssi ignoring Polylang language restrictions.

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().
