The Search Strategy Builder is a tool designed to teach you how to create a search string using Boolean logic. While it is not a database and is not designed to input a search, you should be able to cut and paste the results into most databases' search boxes.
You need to use keywords and Boolean logic when searching for materials in library databases.
Keywords describe the main ideas of your research question - think nouns or short phrases instead of whole questions. Boolean logic is a way to combine your keywords to make your searches more efficient. Boolean operators include AND (narrows your search), OR (broadens your search), and NOT (excludes terms to narrow further).
