Thesauri are helpful when thinking about what search terms you want to use. Some databases have links to a thesaurus on the search page. If you do not mind ads on the page, thesaurus.com is a fast, free tool to find synonyms and antonyms.
Another useful source for developing search terms is the Library of Congress. The LC Linked Data Service has a search box that allows you to search for subject heading, naming authorities, and classifications associated with your desired search term and offers broadened or specific terminologies that you can use in your search.
AND - Search limiter. Results contain all search terms.
OR - Search expander. Results contain at least one of the search terms.
NOT - Search excluder. Results do not contain the specified term.
(Parentheses) - Use perntheses to nest terms within a search string.
"Quotations" - Use quotation marks to search for exact phrases.
N - Append a number to the N to search for a term within the stated number of words of one another, regardless of order entered.
W - Append a number to the W to search for a term within the stated number of words of one another in the order entered.
