Starting with

is stored as
"AND (to,contains,A) AND (subject,contains,A) AND [subject,contains,dummy-dummy-dummy) OR [to,contains,B) AND (subject,contains,B] OR [to,contains,C) AND (subject,contains,C]]"

As an immediate mitigation we will disallow groups following groups, like this:

So into a group, you need to add a term first before starting another group. That's along the lines of your suggestion (quote): I would suggest prohibiting entering second-level nested terms at all.

Yes, that will work. What doesn't work and never worked is this:
