Hi, i implemented the server side search.. but i need also sent to post request for ajax some other parameters

My case:
I have Location input, distance dropdown, send button.
On server side i need get lat and long of central point, find to max distance.

But this i cant send by ajax post which make Datatables.
Must i hack some input field that values of location + distance will set to some parameter and i will create custom logic on server side for this or is same example how to send via post of Datable other params as defined in docs

    You can use ajax.data as a function to send other parameters to the server with the server side parameters.

                        ajax: {
                            url: '{{ path('dt-process-data') }}',
                            type: 'POST',
                            async: true,
                            // dataSrc: ,
                            data: function ( d ) {
                                // i am sending to one php url.. by this parameter i know if go from DT or Editor the reqest to backend
                                // in editor ajax is the same name of parameter but value editor_DataTables
                                d.dataTables = 'viewer_DataTables';
                                // this values are send from form by send button
                                d.getSearchQuery = $('#getSearchQuery').val(); 
                                d.getSearchModule = $('#getSearchModule').val();
                                d.getSearchLocation = $('#getSearchLocation').val();
                                d.getSearchDistance = $('#getSearchDistance').val();
                                d.getSearchDistanceUnit = $('#getSearchDistanceUnit').val();
    
                                // own custom parameters
                                d.test1 = some_js_global_variable;
                                d.test2 =
                                    [
                                        'a', 'b', 'c', 'd',
                                    ];
                                // d.test3 = ['a'=>'b', 'b'=>'c']; // this doesn't works, use instead test4 structure
                                d.test4 = {
                                    a: 'Modul: {{ module }}',
                                    b: 'Search' {{ search }},
                                    c: 'Location: {{ location }}',
                                    d: 'Distance: {{ distance }}',
                                    e: 'Unit: {{ unit }}',
                                };
