Rails - May 2007 - re-filling a form with no model

Probably a basic question here. I have a search form with a bunch of 
criteria in checkboxes, selects, text fields, etc. When the form is 
submitted I''d like it to be re-displayed with the previous values 
(along with search results if any)

I know how to do this with <% form_for @thing %> and assigning @thing to 
an instance of something in the controller. But since the search terms 
are not tied to a model or any other object, they are just in 
params[:terms] for instance - how do you do it easily?

thanks
Sam

Probably not the most elegant solution, but you could just do something 
like this:

<input name="mycheckbox" value="true"
type="checkbox" <%= "checked"
unless params[:mycheckbox].nil? %>>

Good Luck,
