Truncation is shortening a word to its root to enable finding all varients on the word. Truncation uses a variety of symbols, most commonly an asterik (*), but can also be a dollar sign ($), or other character.
For example, If you were searching on varients of children, you would type child*. This search would search for all of the following words:
Some databases allow for wild cards to be embedded within a word to replace a single character. This symbol varies by database and may be a ?, $, #, *, etc.
For example, if you were going to search for both women and woman you might type wom$n.
The symbols used for truncation and wild cards are different in different databases. To determine the symbols in the database you're using, check the online help screens or ask a librarian.
