How to add more custom filters in datatables request?

mstdmstd

in my laravel 8 app with jquery 3.4/bootstrap 4.6 I use dataTable 1.10.19
and I try to add more custom filters and when user enter in search input:

@section('footerscripts')
    <script src="{!!admin_assets!!}/plugins/custom/datatables/datatables.bundle.js"></script>
    <script>
        var oTable= null
        $(document).ready(function () {
            initEducations()

            ...

            function initEducations() {
                var filter_education_category_id = $("#filter_education_category_id").val()

                var filter_document_type = $("#filter_document_type").val()

            var url= 'educations_filter/1/'+filter_education_category_id + '/'+filter_document_type

                oTable = $('#tzdatatables').dataTable({
                    "language": {
                        "emptyTable": "No educations found"
                    },
                    "bServerSide": true,
                    "sAjaxSource": url,
                    "bProcessing": true,
                    "aoColumns": [{
                        "mData": 0 // Sr No
                    }, {
                        "sWidth": "30%",
                        "mData": 1 // Name
                    }, {
                        "mData": 2 // Status label
                    }, {
                        "mData": 3 // Education category
                    }, {
                        "mData": 4 // $created_at_formatted
                    }, {

But it does not work as if filter_education_category_id selected it is not applied to filter.

How can I do it?
