How to expand on maximum of 1000 records in suitelet

HI,

I have a suitelet here that I have written that leverages a saved search to query data from Netsuite.

I have recently discovered that if there are 1000 records returned from the saved search, I cant return any more of these via my suitelet.

Is this possible ? How does one go about getting the total number of records so that i can know how many records are actually in existence ?

Thanks in advance

 function transactionSearch(request,response)   {   try   {     //var custId = '2737';     var custId = request.getParameter('custId');     var type =   request.getParameter('type');  //'SalesOrd';     var searchId = request.getParameter('searchId');  // the internal ID of the search within Netsuite     var lastId = '0';     var isBack = '';       var retObj = [];     var filter = [];       filter.push(new nlobjSearchFilter('internalid','customer','anyOf',custId));          var columns =      [       new nlobjSearchColumn('internalid').setSort(true)      ];          if (isBack)     {       columns[0] .setSort(false);      filter.push(new nlobjSearchFilter('internalidnumber', null, 'lessthan', lastId));     }       var rs = nlapiSearchRecord('transaction',searchId ,filter); // add in a saved search for transactions here.        response.write(JSON.stringify(rs));   }   catch(e)   {   response.write('[{"result" : "no records found"  }]');   }    }
