Google Tips: Boolean & Synonym Searching

Did you know...

Google supports Librarian-approved Boolean operator searching, but just not the way you may be accustomed to?

For example, Google already assumes the AND operator in all searches with two or more words. To use the OR operator, simply use "or" between words or phrases when searching. To use the NOT operator to exclude a search term, choose the minus sign (-keyword). A search for bass -guitar will hopefully yield more results for fish (and beer!) instead of music-related links.

Also, have you ever searched for a keyword but thought that an unknown synonym might be a better choice? By using the tilde character (~), you can perform a similar word search (~keyword).

Great tip, Refman. Thanks.

Perfect! I've been trying to come up with a good example of a "no" search for the computer classes I teach, and that "bass guitar" is perfect. Did you come up with that on your own or did you find it somewhere?
