Boolean operators are words you can use between your search terms to either broaden or limit your search.
1. Use OR to broaden your search and to join SIMILAR terms.
2. Use AND to narrow your search and join DISSIMILAR.
3. Use NOT to narrow your search. This will omit items with that term.
Use quotation marks to search for a phrase.
Use a symbol (* is the most common) to look for variant endings of a word.
