> The new version of Calcite introduces the {{SEARCH}} rex call to express range conditions. However {{SEARCH}}s in conjunctions are currently not simplified. For example, {{AND(=($2, 2020), SEARCH($2, Sarg[2020, 2021]))}} is not simplified while it should be simplified to {{=($2, 2020)}}.
> We can expand the {{SEARCH}} rex calls in {{FlinkRexUtil#simplify}} to achieve this. {{RexSimplify#simplify}} in Calcite will do the rest of the work.
