Boolean Operators
Boolean Operators connect your keywords to create a logical search that the database can understand. This may involve forcing the databases to look for multiple terms/concepts at once, which will make your search more precise. This creates a more power search with a higher percentage of relevant results. This page will show you how to use Boolean Operators AND, OR, and NOT in your database search.
Boolean Operators AND, OR and NOT
Boolean logic defines logical relationships between search terms in a search. The Boolean search operators AND, OR and NOT can be used to create a very broad or very narrow search.
Here are the rules:
- AND combines search terms so that each search result contains all of the terms.
- OR combines search terms so that each result contains at least one of the terms.
- NOT excludes terms so that each search result does not contain any of the terms.
