Boolean Operators are the words AND, OR, and NOT. You use these terms to connect keywords or search words to help you search online databases more effectively and efficiently.
Use AND to connect two unlike words and narrow your search.
Use OR to connect to like words and broaden your search.
Use NOT to exclude a word from your search results.
theat* ~ use for theater and theatre
wom*n ~ use for woman or women
child* ~ use for child or children
By adding an asterisk to the root word you can search for that word with all possible endings.
