Creating custom search on jquery datatables

I need help with customizing jquery datatables search. I need to make main search to work for individual columns. In fact I have to implement this logic (https://datatables.net/examples/api/multi_filter.html) in my main search input, so it have search logic like these individual footer inputs.

I have this code right now but its still not working as expected. Please help...

var table = $('#editable-usage').DataTable();
table.columns().every(function() {
    var that = this;
    $('#editable-usage_filter input').on('keyup change', function() {
        if (that.search() == this.value) {
            that.search(this.value).draw();
        }
    });
});
