Boolean operators allow you to include multiple terms in your search and connect them with the words AND, OR, and NOT. Searching with Boolean operators can help broaden or narrow your search. These terms should be capitalized.
AND - connecting terms with AND will combine your terms and give you more specific results. Example: diabetes AND children
OR - connecting terms with OR will broaden your results by finding more than one search term. Example: elderly OR geriatric
NOT - will exclude a term from your search. Example: lead poisoning NOT children
