Boolean logic

Boolean logic allows the use of AND, OR and NOT to search for items containing both terms, either term, or a term only if not accompanied by another term. The links below and all the Web search engines "search help" have a lot of good examples of Boolean logic. Tip: NOT can be dangerous. Let's say you want to search for items about Mexico, but not New Mexico, so you use NOT to exclude the word New from your retrieved set. This would prevent you from retrieving an article about New regulations in Mexico because it contained the word New, though that wasn't what you intended.
