1.3. Boolean operators

Boolean operators connect your search words together to either narrow or broaden your set of results. Basic Boolean operators are AND, OR, NOT.

Use AND when you need to narrow your results. Using operator AND means that all your search terms must be presented in the resulting records.

Use OR to broaden your results. Using operator OR means that either one or both of your search terms can be presented in the resulting records.

Use NOT to narrow your results. Using operator NOT means that only the first of your search terms can be presented in the resulting records.
