/*
 * Description    : Tests that the SimilarityCheckRule rewrites the similarity-jaccard function with a threshold 
 *                  into similarity-jaccard-check-check if possible.
 *                  Tests that the optimizer drills through the let clause.
 *                  Replacement should happen because of a reverse ">=" condition on the similarity.
 * Success        : Yes
