title: Disable "No matches found" text and autocomplete on select2
body: <p>How do you disable the "No matches found" text on autocomplete on select2/Tagging Support?</p>
  
  <p>This is what I have now:</p>
  
  <pre><code>$('#ProductDescriptions_30_keywords').select2({
          tags:[],
          tokenSeparators: [",", " "],
          minimumResultsForSearch: -1
          }
      );
  </code></pre>
  
  <p>But it still shows the "No matches found" message in autocomplete window. I would like to remove this.</p>
