On TechNet, it clearly says "You can also create a search scope that includes several other scopes."
However, I'm having a hard time figuring out how to do it. What I have is four scopes. What I want is a new, fifth scope that essentially encompasses all of the other four. I'd like to do this by using the existing four scopes, and not have to re-create all of the rules that go into each of those original scopes in the new fifth scope.
Any ideas / insight?
