Multiple Concept Searching

Boolean Operators are protocols that most databases use to enable users to search for multiple concepts at once.

There are Three Boolean Operators: AND, OR, NOT. Click on the pictures for more information.

 

AND

AND narrows a search by retrieving the intersection between topics.

Drama AND Performance Art will only pull up those items that have to do with BOTH types of performance.

OR


OR broadens a search and is especially important for grouping synonyms.

Drama OR Performance Art will pull up items that have to do with either type of performance.

NOT

NOT narrows a search by excluding entire categories of information.

Drama NOT Performance Art will exclude any items that have to do with Performance art, even if they also have to do with drama.
