elasticsearch - 如何在Elastic Search中从JSON字段中删除字段

Question

我想从成员中删除member2。我看了剧本

ctx._source.list_data.removeIf{list_item -> list_item.list_id == remove_id}

列表，但就我而言，它不起作用。那可能吗？

 "_index": "test",
    "_type": "test",
    "_id": "5",
    "_score": 1.0,
    "_source": {
      "id": "1",
      "description": "desc",
      "name": "ss",
      "members": {
        "member1": {
          "id": "2",
          "role": "owner"
        },
        "member2": {
          "role": "owner",
          "id": "3"
        }
      }
    }
  }

Answer 1

您可以使用更新API:

POST test/_update/5
{
  "script": "ctx._source.members.remove('member2')"
}
