Truncation allows you to search any ending on a root word.
For example, if your topic uses the word teenagers, then you may also want to search:
The root word is teen.
To truncate and search teen with any ending type: teen*
Use truncation carefully. You may end up with variations that you didn't anticipate and therefore increasing your results with irrelevant records.
Wildcard symbols can be used in several databases to enhance your search string.
Asterisk wildcard (*): is used between words where variations may be possible. Example: "responsibility * budgeting" can return results such as, "responsibility-centered budgeting" or "responsibility center budgeting"
Question mark wildcard (?): is used to replace an unknown character or you are confused how to write a word. Example: wom?n will end-up for results for women or woman.
