弹性搜索：把一个应该放在一个过滤器中 [英] elasticsearch : make a should into a filter

问题描述

我想用一个过滤器进行搜索，排除不符合条件或不符合条件的结果：

I would want to do search with a filter that exclude result that not match a condition OR anothor condition:

我试图在过滤器中做一个应用，但是失败：

I tried to do a should into a filter but it fails:

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

它引发了这个错误：

 "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
}

你知道我们可以做一个还是一个过滤器？

Do you know if we can do an or in a filter?

推荐答案

p>为什么不简单地 bool / should ，不需要 filter 这里

Why not simply bool/should, there's no need for filter here

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

如果你真的想保持

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