在 Elasticsearch 的 update_by_query api 中获取更新的文档 ID

Question

I use the following query to update some weight filed in matched docs. I need to get the list of updated docs id but I don't know how to do that?

    POST v1_shingle_analyzer/_update_by_query
{
    "script" : {
        "source": "ctx._source.content_completion.weight ++",
        "lang": "painless",
        "_source":true,
        "_source_includes":"_id"
    
    },
    "query": {
    "ids": {
      "values": ["ad22784cde0cecab176811ca9d77e7c2","dssdg784cde0cecab176811ca9fgdfg"]
     
    }
  }
}

References this , this legend answer , this plugin and few ES forum posts, JIRAs.

Short answer:

There is no direct way of doing this. You may need to query again with the IDs to check whether it changed.

Detailed answer:

As per the documentation , Response doesn't have a field to return the updated IDs .

The plugin mentioned is deprecated/dropped the support to context as per the GitHub link. But I think that

1. you can look at the source code to figure out a way to get the IDs updated If it really matters.
2. I see here that there is a response option. We can set three values. But it doesn't say anything about returning IDs. It says options related to which shard, what type is updated, etc.. You can look at this if there is anyway to tweak this.

Kindly let me know for more information.
