elasticsearch：将“应该”变成过滤器

我想使用过滤器进行搜索，排除与条件或另一个条件不匹配的结果：

我尝试在过滤器中执行“应该”操作，但失败了：

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

它会引发该错误：

 "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
}

你知道我们是否可以在过滤器中添加 or 吗？

为什么不简单地bool/should，没有必要filter here

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

如果你真的想保留bool/filter/should构造然后你需要这样做：

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