弹性搜索格式错误查询中的按日期搜索

Question

我正在尝试将按日期范围的搜索与PHP和弹性搜索相结合

$params1 = [
'index' => 'joborders',
'type' => 'joborder',
'from' =>0,
'size' => 50,


     'body' => [

     'query' => [
            'query_string' => [
                'query' => $wildCardString,
                'fields' => ['description'],

                ]
        ]
    ]
];

$filter_date=array();
$filter_date['range']['datecreatedsort']['gte']='2015-11-27';
$filter_date['range']['datecreatedsort']['lte']='2017-11-27';
$params1['body']['query']['filtered']['filter']=$filter_date;
$params1['body']['sort']['datecreatedsort']['order'] = 'desc';

   try {
     $results = $client->search($params1);
     //print_r($results);
   }
   catch (Exception $e) {
$last = $client->transport->getLastConnection()->getLastRequestInfo();
$last['results']['error'] = [];
print_r($last);
}

当我运行上述查询时，我将得到以下错误

query_string格式错误的查询，期望END_OBJECT但找到FIELD_NAME"，"line":1，"col":78}，"status":400} 数据排序字段映射为日期类型为日期，弹性搜索数据库中的值为“数据关联排序”：“2016-05-30T09:39:40.000Z”

请帮助弹性查询中的问题在哪里。

嗨，找到解决办法了，效果很好

$params1 = [
'index' => 'joborders',
'type' => 'joborder',
'body' => [
    'query' => [
        'bool' => [
            'filter' => [
                'range' => [ 'date_modified' => ['gt'=>$duration,'lt'=>$today,'boost'=> '2.0'] ]
            ],
            'must' => [
                'match' => [ 'description' => $wildCardString ]
            ]
        ]
    ]
 ]
];

谢谢你们的帮助。

这是本机elasticsearch请求。

在PHP中，您需要创建具有相同结构的数组查询。

GET /joborders/_search?pretty=true
{
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "created_at": {
              "gte": "2017-11-22 13:49:00",
               "lte": "2017-11-22 23:50:00"
            }
          }
        }
      ]
    }
  }

PS您需要以与db中的datecreatedsort格式相同的格式传递日期范围("2016-05-30T09:39:40.000Z")

试试这个：

{
    "query": {
      "filtered": {
        "query": {
          "query_string": {
            "default_field": "description",
            "query": $wildCardString
          }

        },
        "filter": {
          "range": {
            "datecreatedsort": {
              "gte": '2015-11-27',
              "lte": '2017-11-27'
            }
          }
        }
      }
    }  
}

查询的代码如下所示：

$query=array(
  'filtered'=>array(
      'query' => array(
            'query_string' => [
                'query' => $wildCardString,
                'fields' => ['description'],
                ]
       ),
       'filter'=>$filter_date  
  )
);
