Boolean operators are words used to construct a logical search query. They enable you to boaden or narrow your search terms. Most databases use the Boolean operators and, or, and not and offer these options next to the search boxes when using the database's "Advanced Mode" search option.
OR searches for records that contain any of the terms. Example: A search for Airplanes OR Boats will retrieve records containing either term.
AND searches for occurrences of all of the search terms in a single record. Example: A search for Airplanes AND Boats will retrieve records containing both terms.
NOT searches for records that contain the first term but not the second term. Example: A search for Airplanes NOT Boats will retrieve records containing the first term but not the second term.
