A Relevanssi customer asked whether Relevanssi can slow down a site. They have a slow site and their hosting provider had suggested Relevanssi might be the reason, because Relevanssi had a huge table in the site database. That is true – Relevanssi tables can be really big. But they’re not accessed at all except during…
Often users would like to get a free trial of Relevanssi Premium, but we always say no. Why is that? The answer is simple. We offer our customers lots of liberties. Providing a temporary trial use is difficult. Relevanssi customers have liberties We don’t believe in spying on our customers or restricting their plugin use.…
Sometimes you want to get a specific post as the first result for a certain search, but Relevanssi doesn’t return the right post as the first result by itself for some reason. Relevanssi Premium has a tool for these situations: pinning. Pinning allows you to specify keywords for each post, and whenever that keyword is…

Using the wildcard operators The * operator replaces zero or more characters, so searching for w*ess would match “wilderness”, “witness”, “WordPress” and also “wess”. The…
Relevanssi is language-agnostic in itself. It does not know any language and doesn’t care about which language the site uses. However, there are a few things that you need to consider when using Relevanssi in languages other than English. Characters: use UTF8 As long as your site uses UTF8 characters, Relevanssi can handle just about…
I need to add some custom shortcodes to the list of the “removed” ones (so they don’t show in plain text in the results). However, some of them are built like [shortcode_name text=”Need to keep this in results”] and I would like the content in the text parameter to stay in the results. How do I go about this?…
…$match->doc ]; } else { $current_post_object = relevanssi_get_post( $match->doc ); $minimum_doc_length = 5000; // in characters if ( ! $current_post_object ) { $idl = 1; } else { $post_length = max( $minimum_doc_length, strlen( $current_post_object->post_content ) ); $idl = $minimum_doc_length / $post_length; } $relevanssi_post_idl[ $match->doc ] = $idl; } $match_multiplier =……a boost to shorter posts that have a higher weight and will punish very long posts that rank high just for being long. The version above only considers post content. It does not count the attachment content. This version includes that: add_filter( ‘relevanssi_match’, ‘rlv_inverse_document_length’, 10, 2 ); function rlv_inverse_document_length( $match,…By default, Relevanssi tends to prefer longer posts.

That prefers longer posts as they usually have the search term appear more often. However, a 500-word post with…
