Set initial search value for datatables with AJAX

To setup initial search value of datatables, as per the documentation we can use,

search:
{
    search: "Search text"
}

However, when it is a AJAX table, this will not work. To make it work, we will have to modify our code as,

let searchText = "Search text";
let table = $('#table').on('preXhr.dt', function(e, settings, data)
{
// Set the initial search value
    if (!settings._searchSet)
    {
        data.search.value = searchText;
        settings._searchSet = true;
    }
}).DataTable({
    ajax: 'https://www.example.com/fetch-result',
    serverSide: true,
    processing: true
});
