> HIVE currently doesn't allow multiple subqueries with {{OR}} since calcite has a bug in determining logic for OR expression. See [CALCITE-1546 |https://issues.apache.org/jira/browse/CALCITE-1546].
> Once calcite is released containing fix for the bug HIVE will need to lift the restriction and add tests cases
