MSN search database missint sites?

Has anyone noticed sites disappear from msn search or get wrong
information?
It would seem the msn database has mangled the entry for
www.thunderstone.com. The description shown is some random other site
or something. It looks like maybe something from a google ad by looking
for that full text. Also searching for anything unique to the
thunderstone site comes up with nothing from the site.

Oh sure, now that I post the question some of the site content is
appearing in msn. But the description for the site is still completely
wrong. And searching for things on the home page, like the quoted
phrase "comprehensive text retrieval and publishing" still doesn't
bring up thunderstone.
