Karl,
You could have a document in the index with fields whose names are unique in
the index, e.g.
Document doc = new Document()
doc.Add(new Field("index_info","infokey", Field.Store.NO,
Field.Index.UN_TOKENIZED));
doc.Add(new Field("index_generator",generator_comment, Field.Store.YES,
Field.Index.NO));
indexWriter.AddDocument(doc);
To find the information, search for index_info:infokey and load the field
index_generator.

Subject: Lucene index meta-information
Are there any spaces for writing custom header type information into a
lucene index? I'd like to be able to say something like "this index was
generated with version 3.20.12b of the index generation program with the
following command line ...".
Karl
