Weird routing error.

application.html.erb

<%= form_tag('/posts/results/', {:id => 'search_form'}) do -%>
  <%= text_field_tag :search, nil, {:style => 'display: none;', :id => 'search_field' } -%>
<%- end -%>

error.html

<h2>Routing Error</h2>
<p>No route matches "/posts/results"</p>

post.rb

class Post < ActiveRecord::Base
  
  scope :published, lambda {|val| where(:published => (val == true ? true : false)).order("created_at DESC") }

end

posts_controller.rb

class PostsController < ApplicationController

  def results
    params[:search] = params[:search].blank? ? '%' : "%#{params[:search]}%"
    @posts = Post.where("body LIKE ? OR title LIKE ?", params[:search], params[:search]).published(true).paginate(:per_page => 5, :page => params[:page])
    render :action => :index
  end

end

routes.rb

Blog::Application.routes.draw do

  resources :posts do
    collection do
      get :results
      get :drafts
    end
    
    resources :comments do
      post 'disemvowel', :on => :member
    end
  end
end
