jquery.datatable服务器端分页问题

[流氓兔@23]

使用jquery.datatable进行服务器端分页,可以实现,但有个问题,比如每页显示10条数据,我翻页到第三页,左下角信息会显示"当前显示 21 到 30 条，共 1034 条记录",问题来了,我输入查询条件进行查询,因数据条数少,比如5条,结果信息就会显示为"当前显示 21 到 5 条，共 5 条记录",这样显示明显有问题,请高手指教!
页面代码如下，请求url，返回json数据

function getData_json(){
	var url='/ContentManager/getContentsDataList?contentName='+encodeURI($('#txtSearch').val());
	$('#example').dataTable( {
	    "bAutoWidth":false,
		"bDestroy":true,
		"bProcessing":true,
		"bServerSide": true, //开启服务端处理模式
		"bStateSave": true,
		"sPaginationType": "full_numbers",
		"bSortClasses": false,
		"bFilter": false, //搜索栏
		"bSort": true,
		"bInfo": true,
		"oLanguage": {
			"sLengthMenu": "&{'sLengthMenu'}",
		     "sZeroRecords": "&{'sZeroRecords'}",
		     "sInfo": "&{'sInfo'}",
		     "sInfoEmpty":"&{'sInfoEmpty'}",
		     "sInfoFiltered": "&{'sInfoFiltered'}",
		     "sProcessing":"&{'sProcessing'}",
		     "sSearch": "&{'sSearch'}",
		     "oPaginate": {
		          "sFirst":    "&{'sFirst'}",
		          "sPrevious": "&{'sPrevious'} ",
		          "sNext":     "&{'sNext'} ",
		          "sLast":     "&{'sLast'}"
		      }
		  },
		"sAjaxSource":url,
		"aaSorting": [[0, "asc" ]],
		"aoColumns": [ 
		            {"mData":"contentname"},
		            {"mData":"rener"},
		            {"mData":"lastVersionNumber"},
		            {"mData":"examineState"},
		            {"mData":"contentid"}
		 ]
	});
}

设置"bSort": true，或去掉这个属性。就可以解决这个问题了。
