This is an extremely helpful tip if you find yourself overwhelmed by a high number of search results while searching for information in a database or online search engine. Boolean operators, otherwise known as AND, OR, and NOT, are useful tricks that allow you to search for longer phrases and multiple keywords. The result is fewer, but more relevant, search results.
To learn more about Boolean operators, visit our Search Strategies and Helpful Tips page. There you can print a handout of tips regarding searching with Boolean operators, subject headings, and more.
If visual learning is more your thing, check out this slightly corny but very informative video produced by the Schurz Library at IU South Bend.
