Boolean modifiers, operators, or connectors broaden or narrow your search. They used in the Advanced Search option in the GIL-Find catalog, GALILEO, and other databases.
Parentheses can be used to group Boolean operators.
Quotation marks keep words together as phrases for most databases. However, not all databases or search engines recognize this method. Some databases or search engines use parentheses or single quotes instead.

Truncation uses the asterisk (*) to help you broaden your search to include words with various endings or spellings.
Example: Use educat* to include search results with educate, educated, education, educational, educator.
Wildcards also use symbols to help you find variations of words.
Example: Use wom?n to get woman or women, or use col?r to get color or colour.
Truncation and wildcard symbols vary by database or search engine, but common ones include the symbols *, !, ?, or #. Check the database’s Help page before you search.
