Thanks for the input. In fact, we are using this very query as a Solr
queryFilter (i.e. qf). Is there a specific (Lucene query) syntax to formulate
(force the usage of) such a FieldValueFilter?

Hi,
In Lucene you don't need to use a query parser for that, especially because
range Queries is suboptimal and slow: There is already a very fast query/filter
available. Ahmet Arslan already mentioned that, we had the same discussion a
few weeks ago:

Oops... I take that back! After I clicked Send I realized that this is the
Lucene list - what I said is true for Solr queries, but that is because
Solr added a hack to do things properly, but the Lucene query parser
doesn't have that hack, so Erick is correct.

Say I wanted to find documents which have no content in field1 (or dosuments
that have no field 'field1'), wouldn't that be the following query?
-field1:[* TO *]
Thanks for you help

Should be, but it's a bit confusing because the query syntax is not
pure boolean,
so there's no set to take away the docs with entries in field 1, you need the
match all docs bit, i.e.
*:* -field1:[* TO *]
(That's asterisk:asterisk -field1:[* TO *] in case the silly list
interprets the asterisks
Thx!
