What is Truncation?

Truncation, also called stemming, is a technique that allows you to search for various word endings and spellings simultaneously.

To use truncation enter the root of a word and put the truncation symbol at the end. The database will return results that include any ending of that root word.

Examples:
child* = child, childs, children, childrens, childhood
genetic* = genetic, genetics, genetically

Truncation symbols may vary by database, the most common truncation symbols are the *, !, ?, or #.

Look at the database Help screens to find out which symbol to use.

What are Wildcards?

Similar to truncation, wildcards substitute a symbol for one letter of a word. This is useful if the word is spelled in different ways, but still has the same meaning.

Examples:
wom!n = woman, women
colo?r = color, colour
