Hello guys!  
This is my first time using ElasticSearch so I'm sorry if I missed any documentation.  
So I'm trying to setup a query that will prioritize the document's whose id is in a .txt file that I have. What is the best aproach to do that? Should I upload these ids to a different index and compare them?

Here's what I have so far:

```
GET users/_search
{
  "query": {
    "function_score": {
      "query": { "match_all": {} },
      "boost": "5",
      "functions": [
        {
          "filter": {
            "terms" :{
              "_id": [
                id1,
                id2,
                id3,
                ...
              ]
            }
          },
          "weight": 2
        }
      ],
      "boost_mode":"multiply"
    }
  }
}

```

Thanks in advance!

There is no way in elasticsearch to do queries across multiple indexes. You best choice is to list ids the way you are doing it.
