更新Elastic Search中的信息

问题描述

我有一个问题，我正在尝试更新ES中的对象，因此，每次查询它时，我都会获取所有更新的信息.我有一个像这样的对象:

I have a question, I am trying to update an object in ES, so, every time I query it I will get all the updated info. I have an object like this:

{
  "took": 7,
  "timed_out": false,
  "_shards": {
    "total": 768,
    "successful": 768,
    "failed": 0
  },
  "hits": {
    "total": 456,
    "max_score": 1,
    "hits": [
      {
        "_index": "sometype_1",
        "_type": "sometype",
        "_id": "12312321312312",
        "_score": 1,
        "_source": {
          "readModel": {
            "id": "asdfqwerzcxv",
            "status": "active",
            "hidden": false,
            "message": "hello world",
          },
          "model": {
            "id": "asdfqwerzcxv",
            "content": {
              "objectId": "421421312312",
              "content": {
                 "@type": "text",
                 "text": "hello world"
               }
              ..... //the rest of the object...

我想更新消息(读取模型的一部分)，所以我做了这样的事情:

And I want to update the message (part of the read model), so I made something like this:

PUT test/readModel.id/ID123
{
    "message" : "hello"
}

但是每次我查询ID123时，我都会得到相同的信息(更糟糕的是，我制作的PUT越多，返回的对象也就越多(具有相同的信息)

But everytime I query looking for ID123 I get same info (and even worse, the more PUTs I make the more objects I get back (with same info)

有什么想法吗?

推荐答案

如果只需要更新一个文档，则可以使用更新API 如下:

If there's only a single document that you need to update, you can use the Update API like this:

POST sometype_1/sometype/12312321312312/_update
{
  "doc": {
    "model.message": { ... your JSON object here... }
  }
}

如果多个文档可以具有 readModel.id:asdfqwerzcxv ，并且您要使用相同的 message 更新所有文档，则需要使用通过查询API更新，例如__>

If several documents can have readModel.id: asdfqwerzcxv and you want to update all of them with the same message, then you need to use the Update by query API like this_

POST sometype_1/_update_by_query
{
  "script": {
    "source": "ctx._source.message = params.message",
    "lang": "painless",
    "params": {
      "message": "hello"
    }
  },
  "query": {
    "match": {
      "readModel.id": "asdfqwerzcxv"
    }
  }
}
