Note: Use of this hook will require a manual reindex

When indexing Custom Fields, SearchWP will check to make sure that a Custom Field is in use by engine configuration before indexing it. This is done to keep the index as small as possible. You can use this hook to control whether SearchWP thinks a particular meta key is in use:

Note: This applies to all post types across all engines.

add_filter( 'searchwp_is_used_meta_key', function( $used, $meta_key ) {
// TODO: Determine whether the meta key is in use.
return $used; // true/false
}, 20, 2 );
