1) We are adding a personal preference that enables "Go" search for individuals. If you prefer to go directly to pages when you hit "search" (or hit “enter” after entering a search term), you'll be able to activate that feature for yourself through a checkbox in Special:Preferences. We'll release this change as soon as it's ready. 

Thanks Wikia
