That is the "Solr" answer. But it is slow like hell.
In Lucene there is a natove query named FieldValueQuery already for this. It
requires DocValues enabled for the field.
IMHO, the best and fastest variant (also to Solr users) is to add a separate
multivalued string field named 'fieldnames' w
Thanks..
Which lucene version supports this and what is the performance of such
queries on large set of documents.

Does Lucene provide any API to fetch documents for which a field is not
defined.
Example
Document1 : field1=value1, field2=value2,field3=value3
Document2 : field1=value4,
