Answer 1

  $( "#search" ).catcomplete({
     delay: 0,
     source: data
  });

替换为：

  $( "#search" ).catcomplete({
      delay: 0,
      source: function(request, response) {
         var result = data.slice(0);
         result = $.ui.autocomplete.filter(result, request.term);

        if(! result.length) {
            result.push({
              label: 'No Result Found',
              category: "",
              isPlaceholder: true
            });
        }
       response(result);
     }
  });
