Well, if a search takes 1 minute, the if you repeat search you will be sure to have results that are a little different from the previous ones as users go online/offline oll the time all around the world. (To repeat a search, right-click the tab that displays the keywords used for the search and choose repeat search.)
Also, if you want more results, you can go to Tools, Options and look around: there's an option that allows you to set the amount of results to be displayed. Besides, I don't know if you've noticed, but sometimes, even though the search "meter" says that the search is over, results still come in.
