How do I remove cached information?

Your search engine contains a portion of text from my MySpace profile that I removed at least 6 months ago.

There's a reason I removed it - I no longer felt it was appropriate for it to be there.

What I'd like to know is, how can I remove a portion of sensitive information that should not be there, or at least force the site to refresh that information?

The service needs to realize that people carry on very separate personal and professional lives and it may not necessarily be a good thing for these two to mix.

I need to clear this up ASAP.

Thanks.
