Searching Special Topics with Google

Google Special Searches - Similar to Google Scholar, Google's Special Searches limits search results to specific topics. As this is one of the newest areas in Google there aren't lots of choices. They currently have a Google University Search as well, as various technology platform areas (Apple, Windows, Linux, etc.). Wondering if Apple's new Tiger operating system will support classic mode? The Apple Special Search area is the perfect place to get an answer (by the way... the answer is yes, they will).
