Hey Tim, long time no talk to!
The UUID type isn't a native UUID like you're expecting. It's a String
that gets validated as a UUID at input time. You're probably being
saved by the .toString() method at index time, but that's not going to
help you during retrieval.
You're probably going to want to treat them as Strings in your bean,
with convenience methods to get native Java UUID objects in and out.
