I'm filtering documents based on top left and bottom right coordinates and after that using geohash forming buckets. Each bucket has fixed number of top documents in it. I want to always show for example 60 documents, equally populated in buckets. So if in my result for some geohash precision I have 2 buckets I want to have 30 top hit results in each bucket. Or if result has 10 buckets I want to have 6 top hit results in each bucket. Is there any way to have calculated size of top hits based on number of buckets?

My query:

```auto
{
  "query": {
    "bool": {
      "must": {
        "terms": {
          "category": [
            6
          ]
        }
      },
      "filter": {
        "geo_bounding_box": {
          "type": "indexed",
          "geoLocations.geoLocation": {
            "top_left": {
              "lat": 46.383606,
              "lon": 17.780508
            },
            "bottom_right": {
              "lat": 41.014818,
              "lon": 28.931074
            }
          }
        }
      }
    }
  },
  "aggregations": {
    "large-grid": {
      "geohash_grid": {
        "field": "geoLocations.geoLocation",
        "precision": 5
      },
      "aggs":{
          "document":{
            "top_hits": {
              "sort": [
                {"geoLocations.priority": {
                  "order": "desc"
                }}
                ], 
              "size": 1 <----- this is what I want to be calculated based on number of buckets in geohash aggregation
            }
          }
        }
    }
  }
}

```
