Xrm.Web.retrieveMultipleRecords doesn't return nextLink

Hi Experts,

I am trying to retrieve records using Xrm.Web.retrieveMultipleRecords request with the help of fetchxml but the result doesn't return nextLink.

var fetchXml = "<fetch version='1.0' output-format='xml-platform' mapping='logical' distinct='false' count='1'>" +

"<entity name='contact'>" +
"<attribute name='fullname' />" +
"<attribute name='telephone1' />" +
"<attribute name='contactid' />" +
"<order attribute='fullname' descending='false' />" +
"<filter type='and'>" +
"<condition attribute='lastname' operator='like' value='u%' />" +
"</filter>" +
"</entity>" +
"</fetch>";

var retrieveRecord1 = Xrm.Web.retrieveMultipleRecords("contact", "?fetchXml=" + encodeURIComponent(fetchXml), 1);

I have 3 contact records which satisfies above fetchxml but still I don't get nextLink using fetchxml.
