Description

Currently, we evaluate all the nodes in a filter, regardless to the result of previous evaluation. It makes no sense to evaluate some & node if one node evaluates to 0 or 1. It makes no sense to evaluate some following nodes of a | node if one node evaluate to MAX.

We could probably save a few CPU this way.
