laravel-search初试遇见的问题，求助！

Question

按http://laravelacademy.org/post/3781.html 安装了Elasticsearch（启动后通过curl -X GET http://localhost:9200 测试正常返回信息） 及mmanos/laravel-search依赖 也相应按说明做了配置，最后写了调用程序，程序如下

<?php
namespace App\Http\Controllers\Search;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\Http\Controllers\Controller;
use Mmanos\Search\Search;

class Esearch extends Controller
{
    protected $search;
    public function __construct(Search $search)
    {
        $this->search = $search;
    }
    public function insert(){
        $this->search->insert(
            "post-1",
            array(
                'title' => 'My title',
                'content' => 'The quick brown fox...',
                'status' => 'published',
            ),
            array(
                'created_at' => time(),
                'creator_id' => 5,
            )
        );

    }
    public function res(){
        $results = Search::search('content', 'fox')->get();
        var_dump($results);
    }
}

访问结果如下错误，
