How to make a search results page with pg_search multisearch that has links to the results?

I finally figured out how to implement pg_search's multisearch feature. But I'm having trouble making a usable search results page that displays links back to the various articles and faqs that contain the search terms. It's a pretty basic setup using Rails 3.2.3: Models: I have an Articles and a Faqs model, both with "Title" and "Content" attributes, and this code in both models: ``` include PgSearch multisearchable :against => [:title, :content] ``` Search Form View Code: The search form passes everything to a controller called "results." ``` <%= form_tag result_index_path, method: :get do %> <%= text_field_tag :query, params[:query] %> <%= submit_tag "GO", name: nil %> <% end %> ``` Results Controller: ``` class ResultController < ApplicationController def index @pg_search_documents = PgSearch.multisearch(params[:query]) end end ``` I would like to make a search results page that displays the title of each result found, with a link back to that item. I figured out how to pull the 'class' attribute out @pg_search_documents. My thinking is to do something like this on the results page: ``` <ul> <% @pg_search_documents.each do |pg_search_document| %> <li><%= link_to pg_search_document.searchable.title, "../#{pg_search_document.searchable.class}/#{pg_search_document.searchable.id}" %></li> <% end %> </ul> ``` An example link that this code yields is: `http://localhost/Article/3`. If I could figure out how to downcase and pluralize "pg_search_document.searchable.class", I'd be home free. I've tried writing various methods in the model and controller, and tried writing a helper. But this is where my Rails skills fail me. Any suggestions? Anybody know of a more elegant way of accomplishing this? Any ideas / suggestions are very much appreciated.
