If you would like to be able to go directly to pages, there is an option in Special:Preferences > Under the Hood, scroll down and make sure Enable Go-Search is checked. Like other preferences, this doesn't affect other users, only yourself.

Unfortunately, it is not possible to modify the default functionality of the search feature on a wiki-wide scale by adding a "Go" button for all users. That would be considered a violation of Wikia Terms of Use, as noted here when Wikia updated the search engine last year.
