Is there a way, after IndexWriter.addDocument(), to determine what the

run a search, but the search might not be accurate if the document 
added is only slightly different than another document.

Would an external id be necessary?
As far as I know - yes.
Especially since the lucene document id can change i.e. if you delete a 
document and optimize the index.

Re: Document ID

[Mario Ivankovits]

Hi!

Is there any way to force the document id inside the lucene index, if
I have my own internal numbering scheme, it would be nice to have that
reflected inside the lucene index...anyway?
 
Simply put your ID as additional field to your document. You never 
should rely on lucenes document id as it might change due to delete 
documents during optimize.
