Less convoluted way to query for an empty string?

Hi all,

I can't seem to find a way to query for an empty string that is
simpler than this:

field_name:[* to ""]

Things that don't work:

field_name:""
field_name["" TO ""]

Is the one I'm using the simplest option? If so, is there a particular
reason the other ones I mention don't work? Just curious mostly.

Thanks!
Mat

Yomik recently suggested:
Hmmm, if this is on a String field, it seemed to work for me.
http://localhost:8983/solr/select?debugQuery=on&q=foo_s:""

The raw query parser would also work (it skips analysis):
http://localhost:8983/solr/select?debugQuery=on&q={!raw f=foo_s}
