In my Datatables I use the searchHighlight plugin to highlight the search values...I find it useful.
Now I'm trying to get rid of the standard search form and replace it with custom form/search.
The custom form seems working fine...but the searched values are not highlighted into the Datatables...is there a way to fix the issue?
Thanks a lot for any help.
Below the custom search code:

table.DataTable({
        dom: 'lrtip',
        responsive: true,
        autoWidth: false,
        searchDelay: 500,
        processing: true,
        serverSide: true,
        stateSave: true,
        lengthMenu: [[15, 25, 50, -1], [15, 25, 50, "All"]],
        searchHighlight: true,
        ajax: {
            url: "<?php echo site_url('rmidev/domestic_list')?>",
            type: "POST",
            "data": function ( d ) {
                d.csrf_test_name = token_hash;
                // Read values
                var keyword = $('#exampleInput').val();
                d.keyword = keyword;
            },
            "dataSrc": function ( json ) {
                token_hash = json['csrf_test_name'];
                for(var i=0; i< json.data.length; i++){
                    json.data[i].mm = '<a href="' + controller_url + '/data/' + json.data[i].id + '">' + json.data[i].mm + '</a>';
                }
                return json.data;
            }
        },
        order: [[2, 'asc']],
        deferRender: true,
        columns: [
            {data: 'mm'},
            {data: 'ditta'},
            {data: 'tipo'},
            {data: 'motori'},
            {data: 'nc'},
        ],
        columnDefs: [
            {
                targets: [ 3, 4 ],
                orderable: false,
                searchable: false,
            },
        ],
        "language": {"url": "<?php echo site_url('assets/public/plugins/datatables/lang/dataTables.') . $actual_lang . '.lang'; ?>"},
        "pagingType": "numbers",
    });
};
