Hhhhmmmmm....The Quick Search is working fine for me. Are you typing in what you want to search for in the box on here and not into the search box of your browser? If so you should get results limited to just CS.
You need to type in what youre searching for in the box immediately above where it says "Quick Search". Once the search string is typed in then click on the Quick Search button, or simply hit your enter key.
