> Currently we do not simplify the SEARCH operand in `simplifySearch`. In Hive
> we have run into an issue where we were getting incorrect plans because of a
> missed simplification.
> For example, we would like
> {noformat}
> SEARCH(/($0, CASE(CASE(=($0, 1), true, true), 5, null:INTEGER)), Sarg[1, 2,
> 3]){noformat}
> to be simplified by removing the unnecessary CASEs to
> {noformat}
> SEARCH(/($0, 5), Sarg[1, 2, 3]){noformat}
