Beats me

If they're not in your purchased apps or visible when you search then that usually means the app has been removed from the App Store.

Yeah that usually means that it is no longer available for download. I bought a concert years ago through iTunes and Apple removed it. If I had not made a copy of it, I wouldn't have been able to watch it again.

It is important to note that whenever you purchase digital items, you almost always never actually "own" them. You are licensed to use it, but not actually own it.
