Relevanssi – A Better Search

Omschrijving

Relevanssi replaces the standard WordPress search with a better search engine, with lots of features and configurable options. You’ll get better results, better presentation of results – your users will thank you.

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.

Installatie

  1. Install the plugin from the WordPress plugin screen.
  2. Activate the plugin.
  3. Go to the plugin settings page and build the index following the instructions there.
  4. That’s it!

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.

Uninstalling

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

Kennisbank

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 doesn’t work

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.

Where are the user search logs?

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.

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.

I had some issue due to compatibility with my theme but thanks to the reactivity of the author, I can now enjoy all the functionality of this awesome plugin that definitely improve the search tool. Thanks again !

Wow what a great plugin. Easy to install, excellent documentation, and prompt reply when I asked about a feature, to see if i should upgrade to premium. Miko responded quickly that the feature I wanted was available on the free version - and it was really easy to add its functionality by checking a box. I'm really impressed with the plugin and the quick answer back, and I expect to upgrade when I'm ready for the next level! I have a membership site where I sell individual courses, and the Relevanssi search function will add a lot of value to the site, because people will be able to get a preview of content they haven't purchased yet, that they are actually searching for, which is described in text within paid and locked programs on my site. I can't wait to do more with the plugin. It hadn't occurred to me before that a search plugin could actually help my sales, but I'm excited about this one.

Changelog

4.7.2.1

  • For some reason the plugin files didn’t update in the previous update, ie. 4.7.2 is equal to 4.7.1. This is the real 4.7.2 update.
  • 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.

4.7.2

  • 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.
