- How would you query for all TODO blocks that are tagged or recursively related to ancestor block/page that is tagged with a specific tag? For example, I want all TODO tasks that are tagged as clojure or contained under blocks or pages (in any indentation depth) that are tagged clojure. That way I can see all the clojure related articles I haven't read yet, without having to tag them all explicitly.

- Hey, I try to find Schedules or Due dates that are in-between specific dates, but whenever they contain a marker (TODO, NOW, ...) they should only show if that marker is not completed. Unfortunately, I'm not familiar with Datomic or Clojure at all..

- {{query (and (between -0d ++0d) (task TODO))}}
- d is used to indicate a day. 0d means 0 days or today.
Think of it this way:
Between -0d and ++0d
- = between today-1 and today+1
= between yesterday and tommrow
= today
- ++1d transformed to todays date
+1d transformed to tomorrow
-1d transformed to yesterday
