I needed to add search functionality to my site, and I have done this in 2 methods. First of all I simply added a search menu entry that they can click on to go to a page where they can search. I also added a search bar above my login module. This allows them to type in a search from any part of the site without having to go to a special page. I had previously already changed the formatting of this module using some CSS so there is no module title, and reduced the size of the search bar and the distances between the elements.
I also created my own search button. In the search module parameters you can enable the search button as an image, and explains that the linked image needs to be called 'searchButton.gif'. I created a search button roughly the same size as the search bar so it didn't look too out of place, and styled it to go with the template I am using. I then uploaded it to the appropriate folder using FTP.
