## Jira Link [CALCITE-7815](https://issues.apache.org/jira/browse/CALCITE-7815) ## Changes Proposed Adds support for SEARCH DEPTH FIRST BY ... SET ... and SEARCH BREADTH FIRST BY ... SET ... in recursive CTEs. The generated column can be used in ORDER BY to obtain the corresponding traversal order. The clause is represented by SqlSearchClause on SqlWithItem. During validation, RecursiveWithRewriter builds an ARRAY<ROW<...>> path for depth-first ordering or a row containing depth and keys for breadth-first ordering. SEARCH can be combined with CYCLE. Also updates enumerable comparators to handle composite keys in multi-column sorts and adds Java and iq tests. -- This is an automated message from the Apache Git Service.
