elasticsearch - 弹性-多个过滤器查询语法

Question

您好，我正在执行以下查询:

{
  "_source": [
    "source1",
    "source2",
    "source3",
    "source4",
  ],
  "query": {
    "bool": {
      "minimum_should_match": 1,
      "must": {
        "filter": [
            {
            "term": {
              "_type": {
                "value": "someval1"
              }
            }
          },
          {
            "term": {
              "_type": {
                "value": "someval2"
              }
            }
          }
        ],
        "query_string": {
          "analyze_wildcard": "true",
          "query": "tesla*",
          "rewrite": "scoring_boolean"
        }
      }
    }
  },
  "size": 50,
  "sort": [
    "_score"
  ]
}

当前正在返回:

'"reason":"[bool] malformed query, expected [END_OBJECT] but found [FIELD_NAME]","line":1,"col":343},"status":400}'

任何想法如何在查询上使用多个过滤器？我可以在Elastic 2.4上做到这一点，但是由于OR现在已被弃用和过滤，因此我有点迷失了。

谢谢!

查询的语法错误。不应将filter包装到must语句中。它应该与must处于同一级别。另外bool查询must语句应该是一个数组，而不是对象。因此您的查询应如下所示

{
    "_source":[
       "source1",
       "source2",
       "source3",
       "source4"
    ],
    "query":{
       "bool":{
          "minimum_should_match":1,
          "must":[
             {
                "query_string":{
                   "analyze_wildcard":"true",
                   "query":"tesla*",
                   "rewrite":"scoring_boolean"
                }
             }
          ],
          "filter":{
             "bool":{
                "should":[
                   {
                      "term":{
                         "_type":{
                            "value":"someval1"
                         }
                      }
                   },
                   {
                      "term":{
                         "_type":{
                            "value":"someval2"
                         }
                      }
                   }
                ]
             }
          }
       }
    },
    "size":50,
    "sort":[
       "_score"
    ]
 }

我认为您的过滤器是 OR，这就是为什么我将其包装在 should中的原因
