> Currently MongoDB Adapter not support LIKE operator.
> sql:
> {code:java}
> select state, city from zips where state like 'A%' order by state;{code}
> would error out:
> {code:java}
> java.lang.AssertionError: cannot translate LIKE(CAST(ITEM($0,
> 'city')):VARCHAR(20), 'A%') {code}
> However, MongoDB can achieve SQL-like `LIKE` semantics using `$regex`. we can
