I know I can stop custom SObjects from appearing in the search results by not having a tab for that type. Is there a way to stop Opportunities from being 'searchable'?
The reason is is that I have a customer who has opportunities set as viewable by owner only, with a 'shadow copy' of certain information available to all users (view all checked in profiles). When searching is done via the global search the matching results from both the Opportunities and the custom sObject are shown. I'd like to show the SObject results only.
