How do I clear this cache?

Factual Questions
1

I’m running Windows XP. I’d like to clear the auto fill cache in the Find field for searching for a particular email. Help is no help. Of course.

How do I clear the cache so that when you go to the pull-down arrow in the “Look for:” field, there’s nothing in there?

What application is this in? Outlook? Outlook Express? Another mail client?

And, of course, this is in Outlook.
(That’s kinda important to mention, I’spose.)
