Description
Once we commit #3528, we need to make it easy for apps to enable this with QueryParser.
It seems like it's a "schema" like behavior, ie we need to be able to express the join structure of the related fields.
And then whenever QP produces a query that spans fields requiring a join, the NestedDocumentQuery is used to wrap the child fields?

Research direction
Start by reviewing linked issue #3528 and the QueryParser and NestedDocumentQuery entry points. Determine how the related-field join structure should be expressed and when a query spanning joined fields should be wrapped. Done means applications can enable nested-field handling through QueryParser.
