Hi,
I am using this script:

 <script type="text/javascript" SameSite=Strict
        src="https://cdn.datatables.net/v/dt/dt-1.11.3/b-2.0.1/date-1.1.1/r-2.2.9/sc-2.0.5/sb-1.3.0/sp-1.4.0/sl-1.3.3/datatables.min.js"></script>

I am using Datatables and completely custom layout and everything (as customer required) for searching the table/orders.
Each column has related textbox in some custom dropdown.
When I enter text in textbox 1, which is related to a specific column 1, I save that text in database.
When I enter text in textbox 2, which is related to a specific column 2, I save that text in database as well.
It can be number, text, whatever, doesn't matter at the moment.

When I load the application again, I want to have that search text for specific column 1 loaded in textbox 1 and I want table to be filtered already.

Here is a part of my code, I have lots of events afterwards....

.DataTable({
                //'sdom': 'Rlfrtip',
               ** dom: 'Qlfrtip',**
                select: true,
                'colReorder': {
                    'allowReorder': true
                },
                "sAjaxSource": "/orderlines/GetData",
                "bServerSide": true,
                "bProcessing": true,
                "bSearchable": true,
                "scrollX": true,
                orderCellsTop: true,
                scrollY: $(window).innerHeight() - $(".dataTables_scrollHead").height() - $(".list-toolbar").height() - $(".topbar").height() - 30,
                deferRender: true,
               ** searchBuilder: {
                    preDefined: {
                        criteria: [
                            {
                                condition: '=',
                                data: 'OrderId',
                                type: 'num',
                                value: [56]
                            }
                        ]
                    }
                },**
                scroller: {
                    displayBuffer: 10,
                    boundaryScale: 0.75
                },

SO, when the table is loaded and I wanted to see only orders with orderId = 56, nothing actually happens (it is not filtered at all), here is what the ajax is sending to backend [Notice the last bold attributes/parameters]:

GetData?sEcho=4&iColumns=13&sColumns=OrderId%2CProductName%2CProducerName%2CProdAlias%2CRequestedDeliveryDateStringAll%2CIdent%2COrderDateStringAll%2CCompanyName%2CDepartmentName%2CJobname%2CTotalPrice%2CProductionInfo%2CQuantity&iDisplayStart=0&iDisplayLength=60&mDataProp_0=OrderId&sSearch_0=&bRegex_0=false&bSearchable_0=true&bSortable_0=true&mDataProp_1=ProductName&sSearch_1=&bRegex_1=false&bSearchable_1=true&bSortable_1=true&mDataProp_2=ProducerName&sSearch_2=&bRegex_2=false&bSearchable_2=true&bSortable_2=true&mDataProp_3=ProdAlias&sSearch_3=&bRegex_3=false&bSearchable_3=true&bSortable_3=true&mDataProp_4=RequestedDeliveryDateStringAll&sSearch_4=&bRegex_4=false&bSearchable_4=true&bSortable_4=true&mDataProp_5=Ident&sSearch_5=&bRegex_5=false&bSearchable_5=true&bSortable_5=true&mDataProp_6=OrderDateStringAll&sSearch_6=&bRegex_6=false&bSearchable_6=true&bSortable_6=true&mDataProp_7=CompanyName&sSearch_7=&bRegex_7=false&bSearchable_7=true&bSortable_7=true&mDataProp_8=DepartmentName&sSearch_8=&bRegex_8=false&bSearchable_8=true&bSortable_8=true&mDataProp_9=Jobname&sSearch_9=&bRegex_9=false&bSearchable_9=true&bSortable_9=true&mDataProp_10=TotalPrice&sSearch_10=&bRegex_10=false&bSearchable_10=true&bSortable_10=true&mDataProp_11=ProductionInfo&sSearch_11=&bRegex_11=false&bSearchable_11=true&bSortable_11=true&mDataProp_12=Quantity&sSearch_12=&bRegex_12=false&bSearchable_12=true&bSortable_12=true&sSearch=&bRegex=false&iSortCol_0=0&sSortDir_0=desc&iSortingCols=1&**searchBuilder%5Bcriteria%5D%5B0%5D%5Btype%5D=&searchBuilder%5Blogic%5D=AND&_=1637796753853**

I hope my explanation is clear.
