Is there a "standard" way to store result of query into index?

  1. just storing result of search query in index
  2. store result of aggregation (specially pipeline) query in index.
  3. Is any way to filter aggregated results based on some conditions into index

You would normally do that on the client side by a separate request.

I'm now exaxtly sure what is the ask here but maybe pipeline aggregations, more specifically the bucket selector aggregation can help here.
