Apply rule to read mails

I created a rule and ran it manually, but it only applied to emails that have not been read. I need to apply it to matching criteria from emails that have already been read. How do I accomplish this? I cannot find a way to do it.

cheers

nevermind, I double checked my rule and it was incorrect. I have a rule for subject AND from email. Is there a way to change the rule from AND to OR?
