Now, both of them match numeric nulls if constructed with a "null" value. This is consistent as far as native execution goes, but doesn't match the behavior of SQL = and IN. So, to address that, this patch also updates the docs to clarify that the native filters do match nulls. This patch also updates the SQL docs to describe how Boolean logic is handled in addition to how NULL values are handled. Fixes apache#12856.
