Boolean Operators: Introduction

Boolean Operators

Boolean Operators link concepts and are used to broaden or narrow your search. Briefly, here's how they work:

AND - finds results with your all search terms.  AND narrows your search.

OR - finds results with any of your search terms.  OR broadens your search.

NOT - finds results with only one of your search terms.  NOT narrows your search.

Use the tabs along the top to see more information about Boolean Operators and how to use them.
