Aggregations count

Hi, I'm dealing with problem about aggregation problem with counts of unique documents.

I have two types e_params and e_products. E_products is an parent to e_params.

And i have this query for filtering based on user filters. With this query i count of documents in each params (like color, size, weight).

And this query working good. But not for parameter which user choose. So if user choose color: black. Counts of other params return good. But not the color. That's understandable. But I need to remove the query term of child which sets color: black. And do the aggregations of color on that. Is it possible to do in one query? Or I need to do it with multiple queries? In this count for parameter color i need other queries on parent.

bool => array (1)
must => array (3)
