Wildcards

You can use wildcard characters expressions for rules if Enter a wildcard pattern is in the text box.

The following guidelines apply to wildcard characters:

Asterisks (*) and percent signs (%) serve as wildcard characters. A wildcard character matches zero or more consecutive characters.
Underscores (_) match a single character.
Wildcard characters are automatically applied to the beginning and end of your criteria. Items containing all of your criteria are returned.
You can override automatic wildcards by including at least one wildcard in your criteria. Wildcard characters can be placed anywhere in the box and could return different results depending on the location of the wildcard character. For example, *ed returns all items ending in ed, while ed* returns all items beginning with ed.
To find all items, type a wildcard character (* or %) or leave the box empty.
Leading and trailing spaces are removed.
