Ruben Q L commented on HIVE-29760:
----------------------------------
I'd say arguably simpler, in the sense that we have the same expression with a
single operator (without any logical operator combining several expressions).
Similar to what happens already in the same transformer with:
- NOT EQUALS: x <>0 ; instead of x < 0 OR x > 0
- BETWEEN: x BETWEEN 10 20; instead of x >= 10 AND x <= 20
> Improve SEARCH expansion to exploit NOT_BETWEEN operator

> Improve SEARCH expansion to exploit NOT_BETWEEN operator.
> Currently a search range like "{{{}(-INF, 10), (20, INF)"{}}} is expanded as:
> {noformat}
> x < 10 OR x > 20
> {noformat}
> But we could simplify the expression by using NOT_BETWEEN (i.e. Hive.BETWEEN
> operator with inverse flag enabled):
> {noformat}
> x NOT BETWEEN 10, 20
> {noformat}
