title: How add html and text files to Sphinx index?
body: <p>From Sphinx reference manual: «The data to be indexed can generally come from very different sources: SQL databases, <strong>plain text files, HTML files</strong>, mailboxes, and so on»</p>
  
  <p>But I can't find how add text files and html files to index. <a href="http://www.sphinxsearch.com/docs/manual-1.10.html#quick-tour" rel="nofollow">Quick Sphinx usage tour</a> show setup for MySQL database only.</p>
  
  <p>How I can do this?</p>
