Julian Hyde commented on CALCITE-5625:
--------------------------------------
The problem with expanding ranges is that they sometimes become large
repetitive lists. The repetition makes it more difficult and expensive to apply
further optimizations. There is a good reason why we use SEARCH as the
canonical form and people would be confused if the SEARCH were to be expanded
if the expression crosses an RPC.

> Because the Sarg class is not able to be serialized/deserialized to/from
> JSON, we would like to expand the SEARCH RexNode as a workaround.
