Been searching around quite a bit to find a solution to my problem. Hopefully this is possible with ElasticSearch. I have this query:

```
GET _search
{
  "query": {
    "bool": {
      "must": [
        {"exists" : { "field" : "lvl.keyword" }}
      ]
    }
  },
  "size": 0, 
  "aggs": {
    "player": {
      "terms": {
        "field": "id.keyword",
        "size": 10000000
      },
      "aggs": {
        "min-level": {
          "min": {
            "field": "lvl.keyword"
          }
        }
      }
    }
  }
}

```

Which gives a result like:

```
  "aggregations": {
    "player": {
      "doc_count_error_upper_bound": 0,
      "sum_other_doc_count": 0,
      "buckets": [
        {
          "key": "123",
          "doc_count": 24,
          "min-level": {
            "value": 2
          }
        },
        {
          "key": "456",
          "doc_count": 14,
          "min-level": {
            "value": 1
          }
        },
        {
          "key": "678",
          "doc_count": 14,
          "min-level": {
            "value": 1
          }
        },
        {
          "key": "987",
          "doc_count": 12,
          "min-level": {
            "value": 4
          }
        },
        {
          "key": "476",
          "doc_count": 10,
          "min-level": {
            "value": 5
          }
        }
      ]
    }
  }

```

What I need is a pivot on that result so that I can get an output of how many players have the same "min-level".

```
"min-level", "# of players"
1, 2
2, 1
4, 1
5, 1

```

Is that possible with a pipeline aggregation or what are my options to acquire that data from the initial aggregation?
