>            Priority: Major

> Currently, if table has index on boolean field it can't be used, since queries like
> {code:java}
> SELECT * FROM tbl WHERE a = TRUE
> {code}
> Simplified by Calcite to
> {code:java}
> SELECT * FROM tbl WHERE a {code}
> Condition `{{{}a{}}}` is not supported for building search bounds (see \{{RexUtils.isSupportedTreeComparison()}}) and such an index can't be used.
