-----------------------------------------------------------------------
I gave a quick look at the transformation that _HivePointLookup_ is doing and
there is nothing wrong there, I think you are right [~ghanko] that the problem
lies in the vectorization handling of _IN_ clauses involving _struct_ (turning
off CBO or that specific rule simply prevents the appearance of such clauses,
but they are not the root cause of the issue).

> Project: Hive
> Issue Type: Bug
> Reporter: Ádám Szita
> Priority: Major
> Labels: pull-request-available
> Time Spent: 20m
> Remaining Estimate: 0h
>
> Repro steps:
> {code:java}
> set hive.fetch.task.conversion=none;
> create table test (a string) partitioned by (y string, m string);
> insert into test values ('aa', 2022, 1);
> select * from test where (y=year(date_sub(current_date,4)) and
> m=month(date_sub(current_date,4))) or (y=year(date_sub(current_date,10)) and
> m=month(date_sub(current_date,10)) );
> --gives empty result{code}
> Turning either of the feature below off yields to good result (1 row
> expected):
> {code:java}
> set hive.optimize.point.lookup=false;
> set hive.cbo.enable=false;
> set hive.vectorized.execution.enabled=false;
> {code}
> Expected good result is:
> {code}
> +---------+---------+---------+
> | test.a | test.y | test.m |
> +---------+---------+---------+
> | aa | 2022 | 1 |
> +---------+---------+---------+ {code}
