Boolean Searching

Boolean logic defines logical relationships between terms in a search. Developed by George Boole, a 19th Century English mathematician the Boolean operators are AND, OR, and NOT. You can use these operators to create a very broad or very narrow search.

 "AND" logic

AND : Using AND narrows a search by combining terms.

"OR" logic  

OR : Using OR broadens a search to include results that contain either of the words you're looking for.

"NOT" logic  

NOT : Using NOT will narrow a search by exclusion. (Some search engines, like Google, recognize the minus (-) symbol, instead of the word NOT).

Quotations: Placing quotations around a specific phrase will help you narrow results in order to find information containing that exact wording.
