How do I use Boolean Operators?

Boolean Operators are used when searching the MnPALS Catalog Online, indexes, databases, and some search engines to combine terms or concepts.

AND makes your search more precise by saying both terms must be present: example: anorexia AND teens

OR broadens your search because you are looking for either term. It is usually used for synonymous terms: example: teens OR youth

NOT narrows the search because it eliminates terms: example: anorexia NOT bulimia

More than one operator can be used per search by parentheses for nesting or by using pull-down menus that allow this feature: example: anorexia AND (teens OR youth)
