title: Pg_Search not returning results
body: <p>In my app I have a number of models that i'd like to add multisearch to, I feel like I've done everything required but in the console when I run the following i get back an empty []. </p>
  
  <pre><code>PgSearch.multisearch("Red")
  </code></pre>
  
  <p>so here's what I've done</p>
  
  <pre><code>rails g pg_search:migration:multisearch
  rake db:migrate
  </code></pre>
  
  <p>created an initializer which includes</p>
  
  <pre><code>PgSearch.multisearch_options = {
  :using =&gt; [:tsearch, :trigram],
  :ignoring =&gt; :accents
  }
  </code></pre>
  
  <p>I've also created those extensions</p>
  
  <p>In each of the models i wanted to search I added the following</p>
  
  <pre><code>include PgSearch
  multisearchable :against =&gt; [:name]
  </code></pre>
  
  <p>I then created a results controller, here's whats in there</p>
  
  <pre><code>class ResultsController &lt; ApplicationController
  
   def index
    @pg_search_documents = PgSearch.multisearch(params[:query])
   end
  end
  </code></pre>
  
  <p>I get no errors when running the searches from the console, just no results even though I know there are items that fit what I'm searching for. </p>
  
  <p>Does pg_search go through items created previous to adding pg_search? Does anyone have any clues as to what I'm doing wrong? What I may have missed. </p>
  
  <p>Thanks </p>
  
  <p>Edit: sorry I should also mention I'm using rails 3.2.8 and ruby 1.9.2, I've added pg_search to my gemfile and run rake db:migrate</p>
