用elasticsearch-php laravel為什麼不能返回高亮資料？

    namespace App\Http\Controllers\Search;    use Illuminate\Http\Request;    use App\Http\Requests;    use App\Http\Controllers\Controller;    use Elasticsearch\Client;class Index extends Controller{    protected $client;    public function __construct(Client $client)    {        $this->client = $client;    }    public function search_test(Request $request,$filter='list'){        $word = trim($request->input('word'));        $s=is_null($request->input('s'))?10:trim($request->input('s'));//一頁多少條        $f=is_null($request->input('f'))?1:trim($request->input('f'));//當前頁數        $fr=($f-1)*$s;//當前頁從第一條記錄開始        $params=[            'index' => 's_index',            'type' => 's_type',            'body' => [                'query' => [                    'bool' => [                        'should' => [                            [ 'match' => [ 'title' => $word ] ],                            [ 'match' => [ 'description' => $word ] ],                        ]                    ]                ]                ,'from'=>$fr, 'size'=>$s                ,'highlight'=>[                    'fields'=>[                        'title'=>[]                    ]                ]            ]        ];        $response = $this->client->search($params);        echo "
";        var_dump($response);        echo "
";    } } 

查詢結果都能返回，就是無highlight資料，求朋友幫忙！！！

暫時沒做過搜尋服務，感覺高亮的資料應該在控制器裡面處理的吧。
