What is Boolean? How do I use AND, OR, NOT in my database searches?
Last Updated: Jun 07, 2019     Views: 11

Boolean operators such as AND, OR, NOT can narrow search results (so you get fewer and more specific results) or broaden search results (so you get more search results) if used effectively. Watch the USM Finding Articles (Advanced Search) to learn more about using boolean operators.
