Rails - Jul 2006 - Trouble passing form input to controller action

Hi all,

I''m having trouble passing my form intput from a "view" into
the
controller to perform the qury. I''m looging at teh log and the  
controller is not picking up the values i enter in to the form at  
all. It evaluates to NIL.

Here is the log output

Processing StoreController#display_search (for 127.0.0.1 at  
2006-07-23 21:30:35) [POST]
   Session ID: 161a0485ff2a5bc53dd26ea724e79036
   Parameters: {"commit"=>" SEARCH ",
"product"=>
{"title"=>"cookbook"},
"action"=>"display_search",
"controller"=>"store"}

Here is how i have my code in the controller. Am I missing something?

  def display_search
      @products = Product.find( :all , :conditions => ["title = ?",
@params[:product] ])
      render(:action => ''display_search'')
end

Here is the snippet from my View:

  <%= start_form_tag (:action => ''display_search'') %>
Search for title <%=
text_field("product","title","size" => 40)
%>
<%= submit_tag(" SEARCH ") %>
<% end_form_tag %>




Here is my render action


<% for product in @products %>
<%= h(product.title) %><br/>
<%= product.description %><br/>
<% end %>
