title: termfreq for a phrase
body: <p>I'm using SOLR 4.x termfreq feature in the following example to find "autozero amplifiers" in a field CONTENTS. </p>
  
  <p><a href="http://localhost:8080/solr/select/?fl=contents,documentPageId,termfreq%28contents,%27autozero%20amplifiers%27%29&amp;defType=func&amp;q=termfreq%28contents,%27autozero%20amplifiers%27%29&amp;fq=documentId:49667" rel="nofollow">http://localhost:8080/solr/select/?fl=contents,documentPageId,termfreq%28contents,%27autozero%20amplifiers%27%29&amp;defType=func&amp;q=termfreq%28contents,%27autozero%20amplifiers%27%29&amp;fq=documentId%3A49667</a></p>
  
  <p>I am getting zero frequency for the following paragraph which contains the phrase "autozero amplifiers". </p>
  
  <p>What do I have to do either to solrconfig.xml or schema.xml in order to use termfreq on a phrase not just one word "amplifier"?</p>
