Question

我正在尝试编写一个查询，该查询返回所有不具有特定字段的文档，该字段是嵌套属性，但它不起作用。我正在使用 ES 5.4

{
  "query": {
    "bool": {
      "must_not": [
        {
          "exists": {
            "field": "shares"
          }
        }
      ]
    }
  }
}

我做错了什么？

这是我的映射

这应该有效您已强制执行nested data type映射并使用nested query。

{
  "query" : {
    "nested": {
      "path": "shares",
      "query": {
        "bool": {
          "must_not": [
            {
              "exists" : {
                "field" : "shares._id"
              }
            }
          ]
        }
      }
    }
  }
}

注意：以下设置适用于我。

PUT test_index
{
  "mappings": {
    "document_type" : {
      "properties": {
        "name" : {
          "type": "text"
        },
        "shares" : {
          "type": "nested"
        }
      }
    }
  }
}

POST test_index/document_type
{
  "name" : "vicky"

}

POST test_index/_search
{
  "query": {
    "nested": {
      "path": "shares",
      "query": {
        "bool": {
          "must_not": [
            {
              "exists" : {
                "field" : "shares.city"
              }
            }
          ]
        }
      }
    }

  }
}
