> Currently all double or float fields (trie and point) use (field:[* TO *] OR
> field:NaN) to represent non-DocValue existence queries. However since NaN is
> numerically sorted after +Infinity, we can use this to our advantage and
> just issue a field:[-Infinity TO NaN] range query for point fields.
