add_action('pre_user_query','rudr_extend_user_search');

perform rudr_extend_user_search( $u_query ){
// guarantee that this code might be utilized just for person search
if ( $u_query->query_vars[‘search’] ){

if ( $_REQUEST[‘s’] == $search_query ){
international $wpdb;

        // let's search by customers first title
        $u_query->query_from .= " JOIN {$wpdb->usermeta} fname ON fname.user_id = {$wpdb->customers}.ID AND fname.meta_key = 'first_name'";
        
        // you possibly can add right here any meta key you need to search by
        // $u_query->query_from .= " JOIN {$wpdb->usermeta} cstm ON cstm.user_id = {$wpdb->customers}.ID AND cstm.meta_key = 'YOU CUSTOM meta_key'";

        $search_by = array( 'user_login', 'user_email', 'fname.meta_value', 'psts.post_title' );
        
        // apply to the question
        $u_query->query_where="WHERE 1=1" . $u_query->get_search_sql( $search_query, $search_by, 'each' );
    }
}

}
