How to type wildcard characters

There are two commonly used wildcards, which are mainly used to match text information. They can be used to retrieve documents or verify content. Let’s look at the picture first:

The first type of "*":

The asterisk represents any character, which can be none (null value) or any number of any characters. . Just press Shift 8 (large keyboard) on your keyboard or the * key on your small numeric keyboard.

The second type of "?":

The question mark represents an arbitrary character. This is the only difference. Just type the ? sign on the keyboard.
