Implementing Autocomplete Search

I am not sure how to create an autocomplete form for my search function.

<%= form_tag "/search", :method => "get" do %>
    <%= text_field_tag :query, params[:query] %>
    <%= image_submit_tag "site/blankimg.png", :name => nil %>
<% end %>

I have a next controller that has a configured action

   def query
     @users= Search.user(params[:query])
     @article= Search.article(params[:query])
   end

The model has the following form:

def self.user(search)
 if search
    User.find(:all, :conditions => ['first_name LIKE ?', "%#{search}%"])
  else
    User.find(:all)
  end
end

def self.article(search)
  if search
    Article.find(:all, :conditions => ['title LIKE ?', "%#{search}%"])
  else
    Article.find(:all)
  end
end

Now this work is great for searching, but I want it to show me the result, I am writing this, and I cannot use jquery autocomplete, because these are two objects.
