title: What is the VInt in Lucene?
body: <p>I want to know what is the VInt in Lucene ?</p>
  
  <p>I read <a href="http://lucene.sourceforge.net/talks/pisa/" rel="nofollow noreferrer">this</a> article , but i don't understand what is it and where does Lucene use it ?
  Why Lucene doesn't use simple integer or big integer ?</p>
  
  <p>Thanks .</p>
