Using Wildcard Characters in Filters

To filter lists or text quickly, you can use wildcard characters such as underscore (_) or percent (%), which function as placeholders.
These wildcard characters are supported:
Single Characters
You can enter an underscore (_) as a placeholder for a single unknown character.
Multiple Characters
You can enter a percent (%) symbol as a placeholder for zero or more characters.
Escape Characters
If you are searching for a string with an underscore or percent symbol, add a backslash (\) in front of the special character. The backslash is treated as an escape character.
