Fix your search methodology. Just because you're only interested in OSX related topics does
not mean the rest of the world is. There are many cross-over concepts between the platforms
and many similar API features. And, some things available on OSX are also usable on iOS.
Limiting to the specific forum topic you're under when you search would narrow the search
far too much making it even less useful. Consider, you're in the Cocoa topic but your question
is really about xCode. If search only stuck to the current topic, you'd never find the xCode
info you searched for.
