Aggregation max additional info

Elastic Stack Elasticsearch
1

Hi all,

I have a question if there is a possibility to add some extra fields somehow to the max aggregation result?

My document looks like this:

{
    "updated": {
      "type": "date"
    },
    "scores": {
      "properties": {
        "score": {
          "properties": {
            "value": {
              "type": "long"
            }
          }
        },
        "type": {
          "type": "keyword"
        }
      },
      "type": "nested"
    },
...
}

I want to get max score "values" for each score "type", but I need also "updated" date for each "max" result and I don't know how to do this...

I'm using python elasticsearch-dsl library and I have the first part:

        query.aggs.bucket(
            'scores',
            'nested',
            path='scores',
        ).bucket(
            'type',
            'terms',
            field='scores.type',
        ).bucket(
            'max_score',
            'max',
            field='scores.score.value',
        )

and this is working fine for the aggregation itself but I don't know how to extract "updated" for each max value document.

Appreciate any answer...
Thanks
