So the answer is "yes."

Yes.

Never mind.  I figured it out.  (Don't you hate it when you can't figure =
something out, you write-up a detailed question, post it, then go off an =
figure it out afterwards?)

The problem was the directory was being stored in the index like:

	/path/to/file/

(with the trailing slash).  The delete query, however, didn't have the =
trailing slash since File.getAbsolutePath() doesn't return trailing file =
separator characters.  D'oh!
