Can't you just have two clauses in the query, one that does join and one
that does the same search again but with additional rule of not having a
parentID? Then nested documents match first clause and get "joined" into
the parent record. And non nested documents would match by themselves. I
think you could even use local parameter variables to avoid repeating the
common query.
