* ?
There are many ways to use wildcard symbols and they can vary from database to database, but some typical uses and results involve using the (*) to find words with multiple suffixes. For example:
child* to find: child, children, childhood, childish, etc.
Or using (?) to find multiple spellings of search terms:
wom?n to find texts using “women” and “woman” and "womyn"
Be aware that wildcards do not always guarantee more narrow searches. For example, if you were to input WAR* in a subject search you would get results on wars, warrior, and warfare. However, you may also return words that do not relate to your research interest like warn, warning, wart, warm, warming, etc.
