I'll get the ball rolling....
Sometimes you'll only want results that include an exact phrase. In this case, simply put quotation marks around your search terms. E.g. "cool video games"
If your search term has more than one meaning (bass, for example, could refer to fishing or music) you can focus your search by putting a minus sign ("-") in front of words related to the meaning you want to avoid. For example, here's how you'd find pages about bass-heavy lakes, but not bass-heavy music: bass -music
