Cause: Query Rewrite always chooses the most optimal set
operator materialized view based on parameters, such as
cardinality of the set operator materialized view, number of
branches that the set operator materialized view can rewrite
etc. The set operator materialized view specified was found
to be less optimal.

Action: To force using a set operator materialized view,
consider using a rewrite hint.
