我想将嵌套查询从我的 laravel 控制器传递给 elasticsearch。我的简单查询就像

简单查询

$params = [
            'index' => 'my_index',
            'type' => 'product',
            'body' => [
                    'query'=>[
                        'match'=>[
                            'title'=>'first'
                        ]
                    ]
                ]
            ];
        $response = \Es::Search($params); //passing query from here

效果很好。

如何将以下嵌套查询传递给\Es::Search($params);？

我的嵌套查询：

{   
 "query": {
    "nested": {
      "path": "sku",
      "query": {
        "bool": {
          "must": [
            { "match": {"sku.price": "50"}}
          ]
        }
      }
    }   
  }
}

我是 elasticsearch 新手，所以请给一些建议。

【解决方案1】：

您可以传递嵌套搜索查询，例如：

$params = [
        'index' => 'my_index',
        'type' => 'product',
        'body' => [
                'query'=>[
                'nested'=> [
                    'path'=> 'category',
                        'query'=> [
                            'bool'=> [
                                'must'=> [
                                    'match'=>[
                                        'category.title'=> $catagory
                                    ]
                                ]
                            ]
                        ]
                    ]
                ]
            ]
        ];
    $response = \Es::Search($params);

希望对您有所帮助。

你可以像下面这样传递嵌套查询

$params['size'] = $per_page;
        $params['from'] = $from;
        $params['index'] = config('elastic.Admin_Logs');
        $params['type'] = config('elastic.Admin_Type');
        $params['body']['sort']['meta.datetime']['order'] = "desc";
        $params['body']['query']['filtered']['filter']['bool']['must'][]['match_all'] = [];

            $params['body']['query']['filtered']['filter']['bool']['must'][]['match']['_id'] = $id;


            $params['body']['query']['filtered']['filter']['bool']['must'][]['range']['exceptions.count']['gt'] = 0;

            $params['body']['query']['filtered']['filter']['bool']['must'][]['range']['meta.datetime']['gte'] = $startdate;
            $params['body']['query']['filtered']['filter']['bool']['must'][]['range']['meta.datetime']['lte'] = $enddate;

        $response = $client->search($params);

您好先生，在您的回答中，您已通过 $params['size'] = $per_page, $params['from'] = $from 进行分页。在哪里设置 $from 和 $per_page 以及如何在视图页面上显示分页链接？你能回答我的stackoverflow.com/questions/35719728/… 问题吗？
$per_page = $request->get('limit', 10); $from = ($request->get('page', 1) - 1) * $per_page;
查看以上答案

【解决方案3】：

在控制器 iam 中使用 laravel longaware paginator 方法进行分页

public function getIndex(Request $request)
    {
         $per_page = $request->get('limit', 10);
            $from = ($request->get('page', 1) - 1) * $per_page;

    $params['size'] = $per_page;
            $params['from'] = $from;
            $params['index'] = config('elastic.Admin_Logs');
            $params['type'] = config('elastic.Admin_Type');
            $params['body']['sort']['meta.datetime']['order'] = "desc";
            $params['body']['query']['filtered']['filter']['bool']['must'][]['match_all'] = [];

                $params['body']['query']['filtered']['filter']['bool']['must'][]['match']['_id'] = $id;


                $params['body']['query']['filtered']['filter']['bool']['must'][]['range']['exceptions.count']['gt'] = 0;

                $params['body']['query']['filtered']['filter']['bool']['must'][]['range']['meta.datetime']['gte'] = $startdate;
                $params['body']['query']['filtered']['filter']['bool']['must'][]['range']['meta.datetime']['lte'] = $enddate;

            $response = $client->search($params);
            $access = $response['hits'];
            $admin_exceptions = new LengthAwarePaginator(
            $access['hits'],
            $access['total'],
            $per_page,
            Paginator::resolveCurrentPage(),
            ['path' => Paginator::resolveCurrentPath()]);
       return view('adminexception.index', compact('admin_exceptions'));
}

在你的刀片中使用渲染方法

{!!$admin_exceptions->render()!!}

我收到类似 Class Modules\Catalog\Http\Controllers\Request 在这一行不存在的错误 $per_page = $request->get('limit', 10);
我使用的是 laravel 5.1
我收到 Class 'Modules\Catalog\Http\Controllers\LengthAwarePaginator' not found 错误
如果我使用 $request 是什么，我也收到该错误，请帮助我
use Illuminate\Http\Request;
