Lets say I have 100 records in index1 and 10 records in index2. And I want to get like this:

```
select * from index1 where id not in (select id from index2)

```

Can we have the same above query in elasticsearch or is it even possible.

I have tried with term query its working only for 1 or some ids. I need to filter out around millions of ids from another index. Below is my query:

```
GET index1/_search
{
  "query": {
    "bool": {
      "must_not": [
        {
          "terms": {
        "id.keyword": {
            "index" : "index2",
            "id" : "some_id_value",
            "path" : "id"
        }
    }
        }
      ]
    } 
    
  }
}

```

I am using elasticsearch-7.3.0

Please suggest!

You are trying to do a "join" basically which is not really supported.  
You probably to do that with a batch or similar I guess.

So scroll over all the `_id` from `index2` and for each do a `GET /index/_doc/{id}`. Multiget is probably easier. Or using the [ids query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-ids-query.html).
