title: Issue Performing FullText Search on Entity
body: <p>I'm using neo4j as my backend to a Ruby on Rails project and I'm attempting to implement some search functionality. Bellow is my model:</p>
  
  <pre><code>class Entity &lt; Neo4j::Rails::Model
      property :name
      has_n(:friends).to(Entity)
      index :name, :type =&gt; :fulltext
  end
  </code></pre>
  
  <p>I have created records with the following:</p>
  
  <pre><code>Neo4j::Transaction.run do
    Entity.destroy_all
  
    tony = Entity.new :name =&gt; "Tony Soprano"
    paulie = Entity.new :name =&gt; "Paulie Gualtieri"
    robert = Entity.new :name =&gt; "Robert Baccalier"
    silvio = Entity.new :name =&gt; "Silvio Dante"
  
    tony.friends &lt;&lt; paulie &lt;&lt; robert &lt;&lt; silvio
    tony.save
  end
  </code></pre>
  
  <p>Lastly my search method looks like this:</p>
  
  <pre><code>def search
    terms = params[:q]
  
    render :json =&gt; Entity.all(:name =&gt; terms, :type =&gt; :fulltext)
  end
  </code></pre>
  
  <p>When I run the above search method, I'm getting the following error: <code>no index on field type</code></p>
  
  <p>I've read the <a href="http://neo4j.rubyforge.org/guides/rails3.html#fulltext-search" rel="nofollow">Fulltext Search</a> section of the Neo4j-Rails Guides and I don't see what I'm missing to make this work. My understanding is the :name property should be indexed  because of the way I configured the model.</p>
