    Example function search by title only:

    function __search_by_title_only( $search, &$wp_query )
    {
        global $wpdb;
        if(empty($search)) {
            return $search; // skip processing - no search term in query
        }
        $q = $wp_query->query_vars;
        $n = !empty($q['exact']) ? '' : '%';
        $search =
        $searchand = '';
        foreach ((array)$q['search_terms'] as $term) {
            $term = esc_sql($wpdb->esc_like($term));
            $search .= "{$searchand}($wpdb->posts.post_title LIKE '{$n}{$term}{$n}')";
            $searchand = ' AND ';
        }
        if (!empty($search)) {
            $search = " AND ({$search}) ";
            if (!is_user_logged_in())
