I have a field `cid` that I need to get the distinct elements of. But I need the distinct elements based on when they were added to the database. I want to first do a timestamp range filter, then get the term aggregation of `cid`. I have tried this approach:

```auto
{
	"aggs": {
		"daterange": {
			"range": {
				"field": "@timestamp",
				"ranges": [
						{"from": "2019-05-02", "to": "2019-05-03"}
					]
			},
			"aggs": {
				"result": {
					"terms": {
						"field": "chat_id.keyword"
					}
				}
			}
		}
	},
	"_source":"chat_id"
}

```

But it doesnt aggregate on `cid`.

What's not working?

I'd move that `range` aggregation into a [`range` query](https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-range-query.html) instead, it will be more efficient and give a nicer response format.

You could also use a `date_histogram` aggregation instead, which will generate a bucket-per-time interval.

Otherwise your aggregation looks fine, it should be returning a bucket for each `chat_id.keyword` value.
