Search Page, Browse Items & Search Items buttons

On the advanced search page I am trying to remove the Browse Items and Search Items buttons found at the top of the form. I've removed them from other pages but am unable to find the file that goes with the search page which contains the php function for those two buttons.
If anyone can point me to the file location that would be great. Thanks.

The view for that page is "items/search.php." Most themes won't have their own copy of that, so you'd find it in application/views/scripts/items/search.php.

Copy that to items/search.php in your theme and edit it there.
