Datatables search box is not showing

I am using Datatables and I found that the searchbox is not appearing near the table.

$(document).ready(function() {
                    $('#dfUsageTable').DataTable({
                        pageLength: 10,
                        filter: true
                        deferRender:    true,
                        scrollY:        200,
                        scrollCollapse: true,
                        scroller:       true
                    });
                } );

I have tried adding filter option , but still it is not working.

JSFiddle

I know it's too late, but hope it helps future visitors. add "searching": true, and put , after the filter: true

$(document).ready(function() {
  $('#dfUsageTable').DataTable({
    pageLength: 10,
    filter: true,
    deferRender: true,
    scrollY: 200,
    scrollCollapse: true,
    scroller: true,
    "searching": true,
  });
});
