Wildcards
Wildcards are used whenever it is necessary to match characters.
There are two types:
The Asterisk (*)
The asterisk sign (*) matches zero or more characters. It can be used to match an email address or name by 'isolating' the characters to search.
Example
This would return all data that had this email address surrounded by any characters.
The Question Mark (?)
The question mark (?) matches a single character.
Example
Order? would return any Order that was followed by ONE character.
