Thank you very much @Siferiax !! Your post give a lot of value to my Logseq. Appreciate it a lot.
Also, I can read the query better now thay you have rephrase it and clean it.
If you don’t mind, I have an additional question. Is it possible to validate that the child blocks don’t have this tag neither? Do I need to nest the “not” conditions?
Thanks as always.
