Custom message if tag returns empty results

Hello everyone, using wordpress.

Is it possible to return a custom message if the tag search returns empty?

On my menu i have a link as: www.domain.com/tag/example

I don’t want to remove the link but also it’s a bit annoying if the user presses on this and he sees a blank page. At least a message “sorry there no results for this tag” would do!
