/*
* Description : Fuzzy joins two datasets, Customer and Customer2, based on ~= using Jaccard of their interest sets.
* Customers has a keyword index on interests, and we expect the join to be transformed into an indexed nested-loop join.
* We expect the top-level equi join introduced because of surrogate optimization to be removed, since it is not necessary.
* Success : Yes
