Michael McCandless commented on LUCENE-3133:
--------------------------------------------
I'm confused on why the query parser language would need to be
extended to handle this...
Ie, it seems like, for a given index, the assignment of fields to
parent vs child docs is a global/static decision? And then any query
that has clauses against mixed parent/child fields should be "wrapped"
by NestedDocumentQuery so that the child field/doc matches are
"translated" to the corresponding parent docs?
Why should each query be free to change this?
EG if a user type that same query, but without WITH, then nothing
would match right?
I guess this means I'd vote for 2 :)

> Once we commit LUCENE-2454, 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

> And then whenever QP produces a query that spans fields requiring a join, the
> NestedDocumentQuery is used to wrap the child fields?
