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 : 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. |
