Why is there no way to see all titles?

Through both my phone and my Apple TV I am having a very difficult time finding all titles available to me. I know there is more (currently Radio Days and The Natural, as well as several others) but there is no way to find them without performing an exact search. My question is why would you sell a service then not allow full access to that service?
