How do I get all orders that do not include a specific tag using data service?

You can try to use the `MustNot` to reverse the condition, see [Data service (litium.com)](https://docs.litium.com/documentation/previous-versions/litium-7/architecture/data-service)

This is the code I tried. But I got help from @utku and I believed he has reported a bug for it not working. And he told me to query the “Order” object meanwhile.

```
private static void OrdersNotTaggedWith(FilterDescriptor<SalesOrder> filterDescriptor, string tag)
{
    filterDescriptor.Bool(b => b.MustNot(mustNot => mustNot.Tag(tag)));
}

```

Edit: Correction, he said to create the tags with the Order object instread of SalesOrder object so:

Change this:  
`_taggingService.Add<SalesOrder>(order.SystemId, "MyTag");`

To this:  
`_taggingService.Add<Order>(order.SystemId, "MyTag");`
