Group search results by showing the document with the max or min value of a field

I have checked this tutorial on the documentation of ReactiveSearch.
https://docs.appbase.io/docs/reactivesearch/v3/advanced/groupingresults/

I understand the idea of having aggregationField prop of ReactiveList component to get aggregated data, but is there anyway to decide which document to return?
For example, in the same mentioned example in the documentation, is it possible to show distinct value using the field "brand" but also to show the document that has the max value or min value of for example field "price" instead of showing a random one.

In Elasticsearch that is possible by this query:

{
  "aggs": {
    "2": {
      "terms": {
        "field": "brand.keyword",
        "order": {
          "_count": "desc"
        },
        "size": 50
      },
      "aggs": {
        "1": {
          "max": {
            "field": "price"
          }
        }
      }
    }
  },
  "size": 0,
  "query": {
    "bool": {
      "filter": [
        {
          "match_all": {}
        }
      ]
    }
  }
}

Is that doable in ReactiveSearch?

@malsioufi This is now possible using distinctField, it requires the use of appbase.io service as it relies on server-side query generation.
