Search through the clipboard history

How often do you search through the saved clipboard history?

Do you know that you can use % symbol in the search field as a wildcard character to substitute for any other character or characters in a string?

For example, you can type "john%.com" to find email addresses

johnsmith@hotmail.com
johnsmith123@yahoo.com
johnsmith@gmail.com

That is not frequently used feature, but sometimes it might be really helpful.
