elasticsearch - 部分更新覆盖整个结构

Question

我正在索引具有以下内容的新文档

{
    "lastUpdate" : "20180114144020452",
    "name" : "My Process",
    "startDate" : "20180114162356585",
    "endData" : "",
    "tasks" : [
        {
            "1" : {
                "lastUpdate" : "20180114144020452",
                "taskId" : "123",
                "subject" : "Terceira Atividade",
                "status" : "Active",
                "type" : "userTask",
                "assign" : [
                    {
                        "date" : "20180114144020452",
                        "type" : "role",
                        "name" : "Time 3",
                        "id" : "Team3_345"
                    }
                ],
                "receivedDate" : "",
                "readDate" : "",
                "finishDate" : ""
            }
        }
    ]
}

然后我尝试使用以下更新内容更改task.1.status值

{
    "doc" : {
        "tasks" : [
            {
                "1" : {
                    "status" : "Closed"
                }
            }
        ]
    }
}

但这会覆盖整个task.1结构，删除其他值并仅关闭状态值，而不是保留其他值并仅更改状态值。

我该如何解决？谢谢

您需要通过这样的脚本部分更新来完成此操作

POST updates/update/1/_update
{
  "script": {
    "source": "ctx._source.tasks[0].1.status = 'Closed'"
  }
}
