Why is it that you can only search for content? On some independent wikis there is usually a "Go" button to go directly to the page which makes redirects useful. Is there a way to get this installed or something?
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.
