title: Chosen Drop-down: Implement non-exact search where each word will be invidualy searched
body: <p>I have a code in the fiddle</p>
  
  <p><a href="http://jsfiddle.net/jHvmg/295/" rel="nofollow">http://jsfiddle.net/jHvmg/295/</a></p>
  
  <p>where i have a dropdown which is enabled using chosen-plugin</p>
  
  <pre><code>&lt;select id="drp_menu"&gt;
      &lt;option value="01 - AU -Bingo Campaign1"&gt;01 - AU -Bingo Campaign1&lt;/option&gt;
      &lt;option value="02 - BR-Bingo  Campaign2"&gt;02 - BR-Bingo  Campaign2&lt;/option&gt;
      &lt;option value="03 - CA-Bingo  Campaign3"&gt;03 - CA- Bingo Campaign3&lt;/option&gt;
      &lt;option value="04- US - Bingo  Campaign4"&gt;04- US - Bingo  Campaign4&lt;/option&gt;
  &lt;/select&gt;
  </code></pre>
  
  <p>If I type (bingo) or (ingo) or (ing) in the searchbox, then it displays the filtered list.</p>
  
  <p>If i type (- AU -Bingo) in the searchbox, then it displays the option 1</p>
  
  <p>But if I type (au bingo) it states "No results"</p>
  
  <p>That's because there is no exact occurence of (au bingo) in the option.</p>
  
  <p>But i want to search the option which has both (au) and (bingo) in the option.</p>
  
  <p>Some sort of non-exact search..</p>
  
  <p>How can i achieve this</p>
