Yeah, people really need to know how to google effectively. You can also add "-" before a word to cut out results with that word. (example: "cats -dogs" will return searches with cats but take out ones that also include dogs.)

Then there's "file:" and a file extension name to find searches of that filetype. (example: "AP biology file:ppt" returns all ap biology related powerpoints.

Next there's "site:" and a website. (Example: "site:reddit.com fedoras" searches for fedoras on reddit, a very common thing. Useful if a site's search engine sucks.)
