title: RitaWordNet: getSynset() give nullpointer, but description and id is OK
body: <p>I can search for "health" but "health insurance" give me <code>NullPointerException</code> thrown by <code>getSynset()</code>. </p>
  
  <p>I get the description of "health insurance" and id number 913346773. But I can't get anything from <code>getSynset()</code>. Any good ideas? </p>
  
  <p>Solution: 
  There is a function <code>ignoreCompoundWords(true)</code> by default, I set that to false in constructor and now it returns an array. </p>
  
  <p>New problem: </p>
  
  <p>I can search for "health" and "health insurance", but "Medicare" give me <code>NullPointerException</code> thrown by <code>getSynset()</code>. BUT during debug, the correct description and id is found, so I don't know why getSynset() returns null.</p>
  
  <p>However, checking medicare at: <a href="http://wordnetweb.princeton.edu/perl/webwn?o2=&amp;o0=&amp;o8=1&amp;o1=1&amp;o7=1&amp;o5=&amp;o9=&amp;o6=&amp;o3=&amp;o4=&amp;s=medicare&amp;i=0&amp;h=0#c" rel="nofollow">http://wordnetweb.princeton.edu/perl/webwn?o2=&amp;o0=&amp;o8=1&amp;o1=1&amp;o7=1&amp;o5=&amp;o9=&amp;o6=&amp;o3=&amp;o4=&amp;s=medicare&amp;i=0&amp;h=0#c</a> I just saw that it has no hyponyms. This could be the reason it throws <code>NullPointerException</code>?</p>
