Search Scope (Searching Closed Opportunities/Leads)

Hi,

I cannot search for opportunities or leads that have been closed.

I've tried changing my current list view to include All Opportunities, I've tried searching in all search fields in different locations throughout CRM, no matter what I do - I can't use the search field to find closed opps.

I know the opportunities exist, if I switch view to "All Opportunities" I can see it right there.

Please help.
