@viirya, I agree that we need a separate set of PRs to address the general
problem.
On your comment: "I think the goal to simplify a predicate such as (a > 10
|| b > 2) && (a > 10 || c == 3) to (a > 10) || (b > 2 && c == 3), is to
eliminate redundant filtering expressions running in Filter in execution time."
My two cents: If that is the case, deferring the simplification to the
point just right before the execution time would be an option to consider.
