elasticsearch - elasticsearch:使应该过滤

Question

我想用一个过滤器进行搜索，该过滤器排除不符合条件或其他条件的结果:

我试图对过滤器进行应试，但失败了:

POST /my_index/_search
{
  "query": {
    "bool": {
      "filter": [
        {
          "should": [
            {
              "match": {
                "type1_title": "searched match"
              }
            },
            {
              "match": {
                "type2_title": "searched match"
              }
            }
          ]
        }
      ]
    }
  }
}

它引发该错误:

 "error": {
    "root_cause": [
      {
        "type": "parsing_exception",
        "reason": "[should] query malformed, no start_object after query name",
        "line": 9,
        "col": 21
      }
    ],
    "type": "parsing_exception",
    "reason": "[should] query malformed, no start_object after query name",
    "line": 9,
    "col": 21
  },
  "status": 400
}

您知道我们是否可以执行或过滤器吗？

为什么不简单地使用bool/should，这里就不需要filter了

POST /my_index/_search
{
  "query": {
    "bool": {
          "minimum_should_match": 1,
          "should": [
            {
              "match": {
                "type1_title": "searched match"
              }
            },
            {
              "match": {
                "type2_title": "searched match"
              }
            }
          ]
    }
  }
}

如果您确实想要保留 bool/filter/should构造，则需要这样做:

POST /my_index/_search
{
  "query": {
    "bool": {
      "filter": [
        {
         "bool": {
          "should": [
            {
              "match": {
                "type1_title": "searched match"
              }
            },
            {
              "match": {
                "type2_title": "searched match"
              }
            }
          ]
         }
        }
      ]
    }
  }
}
