title: How do you enable partial matching with "sunspot for rails"?
body: <p>I just have done setting up sunspot_rails and it seems working well except one thing.
  After I made 3 records like below</p>
  
  <ol>
  <li>name=John</li>
  <li>name=John2</li>
  <li>name=John3</li>
  </ol>
  
  <p>when I search with the keyword "John", only 1st record shows up. it looks like complete matching.
  I'd like to have all of them to be appeared as search result.</p>
  
  <p>Is this supposed to be happened as default?
  or did I setup something wrong??</p>
