The -whatever is really good for narrowing stuff down and getting rid of clearly unwanted topics. Also, like HiEy said the define: whatever is good for getting direct definitions.

Using (") before and after search terms is not only useful for searching for phrases, but will also make them more specific. For example, searching on (hat) will get you both "hat" and "hats" in searches, but ("hat") will make sure that they all have "hat" in them, and not just "hats".
Also, (define) will get you a definition for whatever you put instead of "X". It's handy for quickly finding several definitions for a term.
