I would look at the meta data for this, the magic document is something
that I did previously for exactly this problem, and two weeks later we
removed it as so much of the code started having to check if the
document was the magic document.
The only thing with lucene metadata is that solr, currently, does not
expose this.

Thanks for the help. Following-up on that, how can I create document
that is not indexed and returned by "normal" searches, and retrieve it
when I need access to my metadata? There seems to be no reliable
"document id" that I can use for this.

Jochen

There is also commit user data (a String-Map). When you commit the index
writer you can attach that metadata. It's readable by IndexReader.

You could add a dedicated document to the index storing whatever you want.
There is no requirement for lucene docs to bear any relation to each
other.

Hi,
is it possible to add metadata to a Lucene index (not to the
indivudual Fields or Documents contained in the index). We need to
periodically update an index by importing an XML document, and are
looking for a nice cozy place to store an import date and a checksum
that tells us if our input has changed.
Regards,
Jochen
