Yes, it's quite simple (I believe).  My controller (home)  has an
index action.  The index view (index.rhtml) has a search form on it.
I set it up so that the form action is search_by_name action in my
home controller.  The search_by_name action does the:

def search_by_name
     @items = Object.find_by_name( params[:home][:name]
     redirect_to index
end

what I was attempting to do was to run a search, get the @items array
then bring up the index page again with the form but this time display
the results with a FOR loop.
