      Currently we just output a collscan if we see a NOT/NOR. This is too conservative. We should just not descend down a not/nor when tagging the pred tree and go through planning as usual. Enumeration should stop if it sees a negation as well. This way we'll still affix a negation as a filter if there's an and-related pred that can use an index.
