Different fuzzy search setting on different searches

On one of our sites we have 2 search boxes, one where you can do a normal search and the other where you can search for employees or departments. The employees/department search is done by using the relevanssi_do_query() function. Can we use fuzzy matching on the normal search and disable it on the employees/department search?…

Using Relevanssi without a search term

…a search term present. This was originally implemented for a restaurant search, where the users can search for restaurants based on search terms, opening hours and price category. The client wished to be able to use the opening hours and price category with and without a search term. The problem……is, Relevanssi doesn’t trigger without a search term. To fix that, you need to use a new filter hook relevanssi_search_ok. Add this code to your site: add_filter( ‘relevanssi_search_ok’, ‘search_trigger’ ); function search_trigger( $search_ok ) { global $wp_query; if ( ! empty( $wp_query->query_vars[ ‘price‘ ] ) ) { $search_ok = true;……} return $search_ok; } This function will trigger Relevanssi, when the query var price appears in the query.

It needs to have something like this: add_filter( ‘relevanssi_hits_filter’, ‘rlv_hits_filter’ ); function rlv_hits_filter( $hits…

To include taxonomy pages (categories, tags, custom taxonomies) in the search, enable the option on the options page. There’s also the option to choose which taxonomies are included. By default empty terms (not linked to…

Custom weighing with relevanssi_match and relevanssi_results

The relevanssi_match hook lets you modify the matches found for queries. It passes a match object, which has the post id ($match->doc), number of hits found in different parts of the post and the weight assigned to the post ($match->weight). Here’s how Relevanssi calculates the weight: Where $idf is the inverse document frequency, aka the…

Search results breakdown by type

Do you want to have a breakdown of search results by post type? This could be used for example to show a list of post types like books, movies, or albums on a review site, and make them links to limit the search results to that post type. This is fairly easy to do with…
