Why at the bottom? I'm sure it's supposed to be more important than the footer. You could use SmashingMagazine resources when it comes to UX and design. It looks like you made almost all the frequent mistakes:

   Placing the search box at the bottom of the page, or hiding it in the navigation menu.
   Making the input field too short; users are forced to use short, imprecise queries, because longer queries would be hard and inconvenient to read.
   Making the submit button too small, so that users have to point the mouse very precisely.
   Making the search box hard to find.
