Wild Cards

Wildcard characters represent one or more unknown characters. The most commonly used wildcard characters are:

 

* this means any character and any number of them ? This means any one character # This means any one number

 

For example:

 

fun*

 

would mean "any word that starts with 'fun' and has any kind of ending." If you entered "fun*" in a search engine you would get results for fun, funk, funky, funny or any other words which began with "fun".
