Hi all,

actually here is my question:

Maybe some of you have some ideas how to do it.

I think this query from your question on SO is the right direction. I don't fully understand your question, but you do two kinds of filtering on both parent and child side.

You can either do filter by query. You add a query inside the `has_parent`'s inner query instead of the `match_all` query to filter by properties on the parent side. Or build a `bool` query, add the `has_parent` query as must clause and then define another must query with a query to filter on the child side.

Source filtering can be applied on the parent side (modifying the `_source` filtering inside the `inner_hits` element) or child side (adding a `_source` filtering as top level element to the search request).
