### Is your feature request related to a problem or challenge? When I am writing tests in #17319 : In this test, it's intended to do a property check that the output includes 'HashJoinExec`. If such 'contains' check rule can be supported, such tests can be easier to maintain -- If the entire query plan is changed due to other modifications, we don't have to read the diff to verify if the change in this test case makes sense. ``` # Test that IS NOT DISTINCT FROM join produces HashJoin when used alone query TT EXPLAIN SELECT t1.id AS t1_id, t2.id AS t2_id, t1.val, t2.val FROM t1 JOIN t2 ON t1.val IS NOT DISTINCT FROM t2.val ---- logical_plan 01)Projection: t1.id AS t1_id, t2.id AS t2_id, t1.val, t2.val 02)--Inner Join: t1.val = t2.val 03)----TableScan: t1 projection=[id, val] 04)----TableScan: t2 projection=[id, val] physical_plan 01)ProjectionExec: expr=[id@0 as t1_id, id@2 as t2_id, val@1 as val, val@3 as val] 02)--CoalesceBatchesExec: target_batch_size=8192 03)----HashJoinExec: mode=CollectLeft, join_type=Inner, on=[(val@1, val@1)] 04)------DataSourceExec: partitions=1, partition_sizes=[1] 05)------DataSourceExec: partitions=1, partition_sizes=[1] ``` It can look like ``` # Test that IS NOT DISTINCT FROM join produces HashJoin when used alone query TT expect contains "HashJoinExec" <-- Here EXPLAIN SELECT t1.id AS t1_id, t2.id AS t2_id, t1.val, t2.val FROM t1 JOIN t2 ON t1.val IS NOT DISTINCT FROM t2.val ---- ``` ### Describe the solution you'd like _No response_ ### Describe alternatives you've considered _No response_ ### Additional context _No response_ -- This is an automated message from the Apache Git Service.
