Truncation/Wildcard

Truncation enables you to use a search term with variant endings without having to repeat the search. Added to the stem of a word, a truncation symbol will find that stem plus anything that comes after it. The symbol used to truncate a word depends upon the index, database or Web search engine you are using.

environ* will return records on environment, environments, environmental.

* is used as the truncation symbol in Environmental Engineering Abstracts.

$ is used as the truncation symbol in Socrates, Stanford's online catalog.

A wildcard is used to replace one character, but using that wildcard multiple times will replace a fixed number of characters.

wom?n will return records on woman and women. 

w??k will return records with any term that begins with w and ends with k with two characters in between, such as work, week, walk.

Look for the Help links in each database to determine the symbols used.
