Hi Vlad, This is something that you generally can't do. If you have doc values enabled on your fields, you can use Lucene's FieldValueQuery, but beware that this query is very slow. Otherwise if your field is indexed, you can run a TermRangeQuery that has both bounds open but this will be even slower (and by that I mean that this could never return on a large index). So generally the best way to address this problem is to solve it by indexing a meta-data field that contains the list of the fields that a document contains. Then you can filter documents that have a field or not by running a TermQuery against this field.
