Julian Hyde commented on CALCITE-7673:
--------------------------------------
If I understand you correctly, we would not push {{LIKE}} into the Mongo query
and would leave {{LIKE}} to be executed by the consumer (probably
{{{}EnumerableCalc{}}}). If so, see if you can find an economical way to
represent which operators Mongo support, so that it just works for {{{}NOT
LIKE{}}}, {{{}SIMILAR TO{}}}, {{{}COS{}}}, etc.
