I would also think that should work, but it doesn't. If I input exactly "Hugo Award.Best Novel.Winner.1966, Nebula Award.Best Novel.Winner.1966" into the field I get a tree like this "Hugo Award ---> Best Novel ---> Winner ---> 1996, Nebula Award ---> Best Novel ---> Winner ---> 1996"
Not sure why, but as I said the separators don't seem to work. It only sees breaks in one tree and only at the periods.
