 * Description    : Fuzzy joins two datasets, DBLP and CSX, based on the similarity-jaccard function of their titles' 3-gram tokens.
 *                  DBLP has a 3-gram index on title, and we expect the join to be transformed into an indexed nested-loop join.
 *                  We test the inlining of variables that enable the select to be pushed into the join for subsequent optimization with an index.
 * Success        : Yes
