  $("#find").autocomplete({
    source: function(request, response) {
      $.ajax({
        url: "https://query2.finance.yahoo.com/v1/finance/search?q=" + request.term,
        dataType: "json",
        data: {
          term: request.term
        },
        success: function(data) {
           console.log(data)
          var transformed = data.items.map(function(item) {
            return {
              exchange: item.quotes.exchange,
              shortname: item.quotes.shortname,
            };
          });
          response(transformed);
        }
      });
    }
  }).autocomplete("instance")._renderItem = function(ul, item) {
    return $("<li></li>")
      .data("item.autocomplete", item)
      .append("<a>" + item.exchange + "/><br />")
  };
