title: enable_star on SPHINX Search Engine not working
body: <p>I use Sphinx v 0.9.9 and i need to search a <code>substring within a string</code>;</p>
  
  <p>I enabled the start sintax, <code>enable_star = 1</code>, i restarted the entire system and still no results;</p>
  
  <pre><code>index job1
  {
      source      = jobSource1
      path        = /home/sphinx/jobs/job1
      docinfo     = extern
      charset_type    = utf-8
      enable_star = 1
  }
  </code></pre>
  
  <p>I read the docs from here: <a href="http://sphinxsearch.com/docs/current.html#conf-enable-star" rel="nofollow">sphinx start syntax</a> and also <a href="http://sphinxsearch.com/info/faq/#substring-search" rel="nofollow">substring search</a></p>
  
  <p>Any ideas?</p>
