Guys its been reported to me that people are not getting back the results they expect when doing a search using the all sites scope. Looking at the scopes in central admin i've noticed that the items count is only 1020. Is this the number of items available to search on. 1020 seems extremely low for the entire intranet. What does the count refer to?
I dont know if its any help to you but you could try this and see if your search scope is setup properly?
