Redirect to Search on "Not Found"

Given the discussion in http://www.codinghorror.com/blog/archives/000819.html, would it be possible to have the "404" page (for example, http://photos.jjminer.org/v/Events/Weddings/Robin/) include the results of searching for the text that didn't match anything? (if searching is enabled, of course)

If I have time, I'll try to look at the code, but I'm not a Gallery internals person, so it would take me a bit to get up to speed..
