> 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.
