URL formatting

Rails
1

Hi,
The problem i am facing is as follows:

   I want to generate the URL as follows

http://localhost:3000/developments/find/india

As of now MY URL is :

     http://localhost:3000/developments/find?search[address]=India.

The above URL is framed from JQuery by selecting the select box value.

The JQuery i used:

def select_filter_by_city_js
<<-END
  Event.observe($('filter_by_country'), 'change', function(e) {
    window.document.location = '#{search_developments_url}' +

?search[address]=’ + e.element().getValue();
});
END
end

In my routing file(routes.rb) : i defined for search_developments_ur

map.search_developments ‘/developments/find/’,:controller=>
‘developments’,:action=>‘search’

In my controller : I get the value like

def search

location.heading = :search

show_results = params.has_key?(:search)

@title = 'Find Developments ’ + params[:search].to_s
@search = Development::Search.new(params[:search])
@developments = show_results ? @search.run(params[:page]) :
Development.find(:all)

respond_to do |format|
  format.html { render :action => (show_results ? 'index' :

‘search’) }
format.xml { render :xml => @developments }
end
end

I guess i need to work with routes.rb. I tried so many combinations

but no luck . can any one please advise me. what i miss here . Thanks.
