Thanks - can you share the query you're using?

Hi @tomtaylor this is the documentation for the stats aggregation: https://www.elastic.co/guide/en/elasticsearch/reference/8.11/search-aggregations-metrics-stats-aggregation.html
I was surprised that this doesn't follow the standard aggregation.
It seems to be a special aggregation.

Maybe an additional struct StatsAggregation? And then one can match on the values of the map to determine whether to return a Snap.Aggregation or a Snap.StatsAggregation?

Something along the lines of:

  def build_aggregations(aggregations) when is_map(aggregations) do
    Map.new(aggregations, fn 
      {key, %{"count" => _, "min" => _, "max" => _, "avg" => _, "sum" => _} = value} -> {key, Snap.StatsAggregation.new(value)}
      {key, value} -> {key, Snap.Aggregation.new(value)}
      end)
  end

yeah something as simple as that would be awesome, but at a high level elasticsearch/opensearch support 2 types of aggregations, one is called a bucket aggregation which seems to be supported and the other type is a metrics aggregation which isn't.

even if we had a generic aggregation where it just returned the ES data as json it would at least mean that there was some way to get it with Snap
