Bingo!  Code should never do core.getSearcher().get()
since core.getSearcher returns a reference that must be decremented
when you are done.

Using req.getSearcher() is much easier since it ensures that the
searcher never changes during the scope of a single request
and it handles decrementing the reference when the request is closed.
