I am using the latest version of metronic keen theme Datatable search is not appearing . I have enable property of datatable searching:true but still not working

dt = $(tablename).DataTable({
        searchDelay: 500,
        processing: true,
        serverSide: true,
        responsive:true,
        order: [],
        searching:true,
        stateSave: true,
        aoColumnDefs: [
            {
                bSortable: false,
                aTargets: ["nosort"],
            },
        ],
        select: {
            style: 'os',
            selector: 'td:first-child',
            className: 'row-selected'
        },
        ajax: {
            url: url,
            data: filters,
        },


        // Add data-filter attribute
        // createdRow: function (row, data, dataIndex) {
        //     $(row).find('td:eq(4)').attr('data-filter', data.CreditCardType);
        // }
    });

   var  table = dt.$;

    // Re-init functions on every table re-draw -- more info: https://datatables.net/reference/event/draw
    dt.on('draw', function () {
        // initToggleToolbar();
       // toggleToolbars();
        //handleDeleteRows();
        KTMenu.createInstances();
    });
