Elasticsearch painless 找不到某些字段

Question

有类似以下文件：

{
  "lastModified": "2022-01-14T09:33:48.232Z",
  "uuid": "01234567",
  "started": "2022-01-14T09:31:27.651Z",
  "editing": false,
  "approved": true,
  "statistics": {
    "teams": {
      "team1": {
        "name": "Team1",
        "score": 0,
        "winner": false,
        "apiId": "1"
      },
      "team2": {
        "name": "Team2",
        "score": 2,
        "winner": true,
        "apiId": "2"
      }
    }
  }
}

我尝试 select 仅记录其中一个团队具有特定 apiId 的文档。由于 statistics.teams 不是列表而是对象（java 中的映射），我很难实现它。

经过一些常规查询的尝试后，我得到了无痛脚本，但我还是遇到了错误。

有了这个查询

{
  "query": {
    "bool": {
      "must": [
        //{"script": { "script": {"source":  "!doc['editing'].value"} }}
        {"script": {
          "script": {
            "inline": "def statistics = doc['statistics'].value; return doc['editing'].value == params.isEditing;",
            "lang": "painless",
            "params":  {
              "isEditing": 2
            }
          }
        }}
      ]
    }
  }
}

我收到以下错误消息。注释掉的工作正常，无痛找到 editing 属性但不是 statistics

                    }
                }
            }
        ]
    },
    "status": 400
}

Elasticsearch 没有看到根文档的统计参数。

任何人都可以帮我 select 仅在其中一个团队具有特定 apiId 的文档中处理吗？

非常感谢！

您不需要任何脚本即可实现。您可以简单地使用 multi_match 查询来运行对多个字段的查询

POST test/_search
{
  "query": {
    "multi_match": {
      "query": "1",
      "fields": ["statistics.teams.*.apiId"]
    }
  }
}
