elasticsearch - ElasticSearch结合了MUST和MUST_NOT

Question

我需要找到所有包含列表中给定ID且没有字段“device_data”的文档。

我的搜索查询:

{
    "query": {
      "bool" : {
        "must" : [
          {
            "terms" : {
              "id" : [
                "1cbe0c01-6e0c-11e8-b79f-097b2a39b616"
              ]
            }
          }
        ],
        "must_not" : [
          {
            "exists" : {
              "field" : "device_data"
            }
          }
        ]
      }     
    }
}

仍然返回此文档，我希望在该文档中找不到“device_data”。我究竟做错了什么？

                }
            }
        ]
    }
}

您需要使用一个终端字段，例如device_data.id:

    "must_not" : [
      {
        "nested": {
          "path": "device_data",
          "query": {
            "exists" : {
              "field" : "device_data.id"
            }
          }
        }
      }
    ]
