Sounds good. "OR" in the negation of any query that matches any possible
value in a field.
The Solr query parser doc lists the open range as you used:
-field:[* TO *] finds all documents without a value for field
See:
http://wiki.apache.org/solr/SolrQuerySyntax
This also include pure wildcard that can generate a PrefixQuery:
-fname:* OR fname:(A B C)

Subject: syntax for negative query OR something
How do I search for things that have no value or a specified value?
Essentially I have a field that *may* exist and what the absense of a
field to also match.
I have a few variations of:
-fname:[* TO *] OR fname:(A B C)
Thanks for any pointers
