We are investigating splitting nested documents up into parent/child documents.

I'm wondering, how can we query/search for a document of a specific type? E.g. we index questions and answers, and want to be able to efficiently search for questions or answers regardless of the relationship.

We don't want to invest into `_type` since it's being deprecated and removed. `has_child`/`has_parent` queries have performance warnings about using them in the docs. What is the correct way to achieve this?
