Relevanssi – A Better Search

Descripción

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.

Instalación

  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

Knowledge Base

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.

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.

I had a pleasure of using this plugin for some time and it was great. Fantastic functionality and as I recently found it also has fantastic support from plugin authors (Mikko specifically). I hope I can go for a premium version of the plugin for my future project.

Beaucoup d’options de configuration et assez simple à utiliser

I used Relevanssi for maybe 5 years and it’s one of the first plugins I add to any WP install. Personal customization is spot on, so that you get the output as you wish to convey it to your site. The depth of categorisation scans is beyond impressive and personally I see no effect on load time anywhere. Scans are super fast as are searches.. I have also added the Ajax pop-up plugin that saves users and servers a page load and takes you straight to that particular page required. The whole package is a killer engine. So much so it makes me wonder it’s not THE search engine in WP. I have only needed support once in my life when wp 6.5 launched. The fix from Mikko was immediate and very friendly, helpfull and competent. I operate in TT4 (Block themes), that these “years” transition to work smooth and stable. Relevanssi is maybe the one plugin that never caused any issues. It runs flawlessly in WP and also Woocommerce and even my multi vendor art fair I currently run at svalinnart.com. Feel free to test Relevanssi live there, if you so wish. Thx Mikko for this. It’s very appreciated on a daily basis!
