Dataview: how to exclude specific tag

[Missionary]

Steps to reproduce

• I use Dataview plugin to list all the notes within a folder, named “MacBook”. I would like to list only notes without tag: #Mac/App as the list of wanna-buy-apps.

```dataview table image, price, purchase_date from "MacBook" where file.tags != "#Mac" and file.tags != "#Mac/App" ```

• I also tried where file.tags != "Mac/App" and where file.tags != #Mac/App but none of these actually work.

Question

• What is the actual code to exclude a nested tag ?

Hi.
Maybe this:

```dataview
TABLE
	image,
	price,
	purchase_date
FROM "MacBook" AND -#Mac/App
```
