Brizy is another WordPress site builder and as usual, it too has hard-coded queries that don’t play nice with Relevanssi. Fortunately, the Brizy post loop also has a filter hook for adjusting the loop arguments, so you can make Brizy use Relevanssi with a simple function. Add this to your site:
add_filter( 'brizy_post_loop_args', function( $args ) {
$args['relevanssi'] = true;
return $args;
} ); This turns on the relevanssi flag in the query parameters. This makes Relevanssi capture the query and run the search.
