[~rusanu], _processRange_ in RexSimplify should be simplifying {{$1>10 AND $1>20}}, you might want to take a look at why that logic is not being triggered.

> Expressions such as {{$1<>1 and $1=2}} can be simplified to {{$1=2}}. Similar {{$1>10 AND $1>20}} can be simplified to {{$1>20}}. Such expressions are produced by the proposed solution for CALCITE-1790 (simplify boolean CASE to complex AND/OR).
