Give extra weight if a search matches a certain custom field

  • I see in the documentation you can add weight based on custom field but it’s not clear to me how to do the following:

    I have an ACF custom field called “author_search”. If the search term matches the text in “author_search” i want that result to have extra weight.

    There will be multiple authors in the “author_search” custom field. An example value is “john smith jane doe” … no commas. So searching for John Smith or Jane Doe should add extra weight to that result.

    Thanks!

    This would be easier with Relevanssi Premium. With the free version, the solutions using the relevanssi_match hook require you to check the custom field for each post, which adds many extra database calls.

    Here’s a solution that only makes one extra database call:

    add_filter( 'relevanssi_results', 'boost_author_search' );
function boost_author_search( $results ) {
    $query = get_search_query();
    $authors = relevanssi_get_post_meta_for_all_posts( array_keys( $results ), 'author_search', true );
    array_walk(
        $authors,
        function( $value, $post_id ) use ( &$results, $query ) {
            if ( stripos( $value, $query ) !== false ) {
                $results[ $post_id ] *= 100;
            }
        }
    );
    return $results;
}

    If the search term is found in the author_search field, the weight for the post is multiplied by 100.

    Ah, since you mentioned in the other thread you’re using Search & Filter, I’m not sure if get_search_query() works with that… but S&F support can help you figure out a way to access the search query if necessary.

    This may also work:

    global $wp_query;
$query = $wp_query->query_vars['_sf_s'];
