searchwp_query_join

If you would like to manually JOIN more tables during the main search query, this filter will allow you to inject your own JOIN clause.

Example: To include your own JOINs, add the following to your active theme’s functions.php:

      
        <?php
      
        function my_searchwp_query_join( $sql, $postType, $engine ) {
      
          // modify $sql to your liking
      
          return $sql;
      
        }
      
        add_filter( 'searchwp_query_join', 'my_searchwp_query_join', 10, 3 );
