Range filter on bucket aggregation

[benes12 (Ben)]

I could have sworn there was a way to do this, but basically I'm trying to apply a from and to range on a sum from another agg.

{
  "size": 0,
  "query": {
    "bool": {
      "must": [
        {
          "range": {
            "@timestamp": {
              "gte": "2018-06-01T00:00:00Z",
              "lte": "2018-06-30T23:59:59Z"
            }
          }
        },
        {
          "term": {
            "group_id": 883
          }
        }
      ],
      "must_not": [
        {
          "term": {
            "type": "daily_usage"
          }
        }
      ]
    }
  },
  "aggs": {
    "users": {
      "composite": {
        "size": 5000,
        "sources": [
          {
            "account_id": {
              "terms": {
                "field": "account_id",
                "order": "asc"
              }
            }
          }
        ]
      },
      "aggs": {
        "bw_sum": {
          "sum": {
            "field": "bandwidth"
          }
        }
      }
    }
  }
}

Is the original query. What I'd like to do is add a range to only return results where the bw_sum is between 0 and 2000000000. We currently do it with a script, but on millions of docs it's taking an obvious long time.

Is there a way to only return results via post search filter using a bucket agg result or even return the count within the bucket if the sum is within range?
