| * Description : Fuzzy self joins a dataset, Customers, based on the edit-distance-check function of its interest lists. |
| * Customers has a keyword index on interests, 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 |
