Hi,  
I have two documents (?) with 3 index:

```
@timestamp request_id exit process_id
May 18th 2018, 17:17:36.074 965ff327-5aae-11e8-a5e5-196607b31323 - 96608fdb-5aae-11e8-98d0-4d98e324480e
May 18th 2018, 17:17:35.324 965ff327-5aae-11e8-a5e5-196607b31323 400 - 

```

As you can see request\_id is the same for both documents, but in one case exist `exit`  
but not `process_id` and vice-versa. What I would is having a saved search result in Kibana that will return something like that:

```
@timestamp request_id exit process_id
May 18th 2018, 17:17:36.074 965ff327-5aae-11e8-a5e5-196607b31323 400 96608fdb-5aae-11e8-98d0-4d98e324480e

```

I have aggregate the result based on request\_id:

```
GET cwl-2018.05.18/_search
{
  "size":"0",
  "aggs" : {
    "aggregate_req_id" : {
      "terms" : { "field" : "request_id.keyword" }
    }
  }
}

```

Now I have a response with result of aggregation, sayng that for each bucket there are two documents. I would _vertically coalesce_ that aggregation, so each bucket has a single document. I'm searching for resource but i can't find no more

There's currently no way to do that sorry to say.
