Boolean logic is a system named after British mathematician George Boole and refers to the relationships among search terms. Boolean logic uses various combinations of the logical operators OR, AND, and NOT to narrow and refine search results. Three examples of logical, or Boolean operators, follow. Notice the use of parentheses to avoid any possible ambiguity.
