Boolean operators are words (AND, OR, NOT) that expand or narrow search parameters when using a database.
| Boolean Operator | Function |
| AND | Provides results that contain all keywords. Using AND between search terms will narrow your results. |
| OR | Provides results that contain either (or both) keywords. Using OR between search terms will broaden your results. |
| NOT | Provides results that contain the first keyword but not the second keyword. Using NOT between your search terms will narrow your results. |
