title: Twitter jQuery typeahead - How to remove the cache
body: <p>I made a query like this... and first time, it ran the filter... cool, and it worked...</p>
  
  <p>But now there are more entries, and it seems to be running off of cache. How do I force it to stop using the cache?</p>
  
  <pre><code>var countries = new Bloodhound({
      datumTokenizer: function (d) { return Bloodhound.tokenizers.whitespace(d.name); },
      queryTokenizer: Bloodhound.tokenizers.whitespace,
      limit: 10,
      prefetch: {
          url: Url + '/Country/JsonList',
          filter: function (list) {
              return $.map(list, function (country) { return { name: country.Name }; });
          }
      }
  });
  
  countries.initialize();
  
  $('.countries.typeahead').typeahead(null, {
      displayKey: 'name',
      source: countries.ttAdapter()
  });
  </code></pre>
