Is it possible to exclude different task completion types?

[Shadocvao]

So I can exclude all checked tasks by using !checked however I'm using Alternate Checkboxes, and would like to be able to see tasks like [?] (question) and [/] (half done) etc... but I want some to be hidden such as[>] (forward) and wondered if there was a way to do this through dataview that I can replace the !checked with.

I'm currently using the tasks plugin for different type of tasks and task tracking, so would like to be able to do this through dataview where possible. Many thanks.
