Aleksey Plekhanov updated CALCITE-5288:
---------------------------------------
Summary: Expression '(a > 5 and a < 15) or (a > 10 and a < 20)' should be
simplified to 'SEARCH(a, Sarg[(5..20)])' (was: Expression '(a > 1 and a < 3)
or (a > 2 and a < 4)' cannot be simplified to 'SEARCH(a, Sarg[(1..4)])')
> Expression '(a > 5 and a < 15) or (a > 10 and a < 20)' should be simplified
> to 'SEARCH(a, Sarg[(5..20)])'

> Key: CALCITE-5288
> URL: https://issues.apache.org/jira/browse/CALCITE-5288
> Project: Calcite
> Issue Type: Bug
> Reporter: Aleksey Plekhanov
> Assignee: Aleksey Plekhanov
> Priority: Major
>
> If there is only one range in search/sarg after simplification, the result of
> sarg collector is ignored (\{{SargCollector#needToFix()}} method).
> Expression {{(a > 1 and a < 3) or (a > 2 and a < 4)}} is simplified to
> {{OR(SEARCH(a, Sarg[(1..3)]), SEARCH(a, Sarg[(2..4)]))}} but expected
> {{{}SEARCH(a, Sarg[(1..4)]){}}}.
> If there are more the one intervals or if open interval exists, expressions
> simplified as expected.
