Aleksey Plekhanov commented on CALCITE-5288:
--------------------------------------------
[~julianhyde], thanks, I've changed the subject and example.
What about proposed fix? (I've prepared and attach the pull request with
described changes)
> Expression '(a > 5 and a < 15) or (a > 10 and a < 20)' should be simplified
> to 'SEARCH(a, Sarg[(5..20)])'

> 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 > 5 and a < 15) or (a > 10 and a < 20)}} is simplified to
> {{OR(SEARCH(a, Sarg[(5..15)]), SEARCH(a, Sarg[(10..20)]))}} but expected
> {{{}SEARCH(a, Sarg[(5..20)]){}}}.
> If there are more the one intervals or if open interval exists, expressions
> simplified as expected.
