Truncation or wildcard symbols allow you to look for variations of words. They often broaden your search results.
Example: searching on sport* would bring up variations such as sport, sports, sporting, sporty, etc.
Note: The truncation symbol is usually an asterisk (*) but can vary by database. Consult the database’s “help” or “search tips” pages for details.
Use quotation marks for phrase searching, i.e. "University of Georgia"
Note: searching "social work" tells the database to look for these words in this exact order - this phrase, instead of finding social in one sentence and work in another.
