Hi Walter,
As per http://microsite.omniture.com/t2/help/en_US/reference/index.html#Referrer_Type_Report
"Search Engine: Search engine referrers are recorded when visitors use a search engine to access your site. The referring value must be considered by Adobe to be a search engine, and cannot be a subdomain that is not considered a search engine (e.g. mail.google.com is not a search engine since that's their Gmail domain)."
So Google is listed under other website means that referrer might not be coming from Google search but from other subdomains of google like gmail, etc.
Let me know if it helps you. You can also mark it as closed.
Thanks
Akhil
