(n00b) Meaning of Hits.id (int)
Hello everyone.
I'm in the process of writing "my first lucene app", and I've got to the
bit where I get my search results back (very exciting! ;).
My documents are not stored in their original form by lucene, but in a
seperate database. My lucene docs do however store the primary key, so
that I can fetch the original version from the database to show the user
(does that sound sane?)
I see that the 'Hits' class has an id (int) method, which sounds
interesting. The javadoc says "Returns the id for the nth document in
this set.". However, I can't find any mention anywhere else about
Document ids. Could anybody explain what this is?
Many Thanks in Advance,
Peter Pimley, Semantico

It's lucenes internal id or document number which allows you to access
the document and its stored fields.
See
IndexSearcher.doc(int i)
or
IndexReader.document(int n)
The docs just don't name the parameter 'id'.
