Returning empty set?

[plettb]

This is just a simple question: is it possible to return an empty set rather than a "NotFound"? In my mind this could be handled in a variety of ways, either on the server side or the client side. I'm just wondering if there is already some kind of solution, or if I have to go with exception handling on the client.

I looked through the documentation and didn't see anything. If it's documented, please point me to it and forgive me for wasting your time. :)
