示例1: CombinePredicates
// <summary>
// Combine two predicates by trying to avoid the predicate parts of the
// second one that are already present in the first one.
// In particular, given two nodes, predicate1 and predicate2,
// it creates a combined predicate logically equivalent to
// predicate1 AND predicate2,
// but it does not include any AND parts of predicate2 that are present
// in predicate1.
// </summary>
