Dataview shows all tasks on a page, rather than only the ones specified in the query about obsidian-dataview HOT 1 OPEN

When you specify tags outside of a task definition it's applied to the entire page, and not specific to that task. This means that when you do a task query like yours where you're asking for tags related to a particular tag it'll list either specific tags related to that tag, or all tasks from pages tagged with that tag.

In order to make the tag related to the task it self you need to do something like:

- [ ] project B #todo/Business

There are also two other methods to do this, and that would either to only have business related todos in your entire file, and keep the #todo/Business tag, or potentially you could also limit your task query to a particular section of your note:

## Business

- [ ] project B

... Further down or in another note ...

```dataview
TASK
WHERE meta(section).subpath = "Business"
```

In either case, this is not a bug, but more of a misunderstanding on how to tag tasks.
