Truncation and Wildcard

Two types of truncation symbols are used in Cuesta's periodical database EBSCOhost. The first, represented by a question mark, is called a wildcard. Added anywhere in a word, it will find all the words that can replace the symbol with a letter. The symbol used to find all endings of a particular word stem uses an asterisk.

ne?t will return words like neat, next or nest.
? is used as the wildcard symbol, because it can be used for any letter .
environ* will return records on environment, environments, environmental.
* is used as the truncation symbol.
