Sortable list search

Hi I think I have a simple problem, but I just can't find the solution
I just found a very simple sorting solution in a book something like
that
It works in the first page with localhost/faculdade?sort_by=name
but when u try to go to the next page it goes to
http://localhost:3000/faculdade?page=2 I know it should be
/page=2&sort_by=name but don't know how to do it .....
Thanks in advance !

#on list.rhtml

<table border="1" cellpadding="5" cellspacing="1">
  <tr>
  <th> <a href="?sort_by=nome">Name </a> </th>

<%= link_to 'Next page', { :page => @faculdade_pages.current.next } if
@faculdade_pages.current.next %>

and on the controller
  def list
    sort_by = params[:sort_by]
    @_pages, @faculdades = paginate :faculdades, :order => sort_by,
:per_page => 20

This should do the job.
<%= link_to 'Next page', { :page =>
@faculdade_pages.current.next, :sort_by => params[:sort_by] } if
@faculdade_pages.current.next %>
