Boolean Operators are used to connect two, or more, keywords together as a way to narrow or expand your search results.
AND - narrows your topic; only results with the terms 'women' and 'media' found in the title, subject heading or description will be shown.
OR - expands your topic; useful when you want to add to your results; this terms works well when using synonyms as keywords.
NOT - removes results; if your keyword can be defined in multiple ways. For example, 'image' can mean pictures but it could also be related to body image or self-esteem.
