Using Angular ng-resource with multiple query parameters

I'm trying to send a request to the server with 4 parameters. It seems to work with less than 4, but I cannot get it to work with 4 or more. Here are the snippets:

        historyy: $resource('/history/:user.:item.:count.:cost', {

            user: '@userr',
            item: '@itemm',
            count: '@countt',
            cost: '@costt'
        }

Calling RestService:

   RestServices.historyy.get({userr: "Asd",itemm: $scope.item.id,countt: amount,costt: '0' });

When I execute this, the URL looks like this: http://localhost:8080/history/...?costt=0&countt=6&itemm=1&userr=Asd

Why is it adding these crazy (...?) ?. When I remove one of the parameter (no matter which one) it works properly.
