Is there a way to bring up a permanent twitter search, so you can archive the ones you've seen after you've read them?

I love the messages window. I've got all my D's and @'s in one place, and I can archive them once I've read them.

Now I want to include a search for my company name, so I can attempt to reach out to people talking about us, but not D'ing or @'ing us directly.

For Kiva.org, lots of people still don't know we're on Twitter, so I'd like to reach out to them even more
