Done ;)

            $subquery  = "( SELECT 1 AS rnk, images.* FROM images WHERE title REGEXP '[[:<:]]{$q}[[:>:]]' 
                            UNION SELECT 2 AS rnk, images.* FROM images WHERE tags REGEXP '[[:<:]]{$q}[[:>:]]') query";
        $images    = Images::select(['categories.name', 'categories.slug', 'images.*'])
                        ->join('categories', 'images.categories_id', '=', 'categories.id')
                        ->join(\DB::raw($subquery), 'query.id', '=', 'images.id')
                        ->where('images.status', 'active' )
                        ->groupBy('images.id')
                        ->orderBy('query.rnk' )
                        ->paginate( $settings->result_request )
                        ->appends(request()->query());
