Hello back,

according to the JavaDoc it means:

"Returns the stored fields of the nth Document in this index."

In your case than if would mean the greater n the younger the doc. However I
am not sure how you can create such an index. I think you should have a look
to the Luke project, which allows you ot access and  look into Lucene
Indices.

If I did not answer your question, please explain a little bit further...

Karl

Yes, documents with lower numbers were indexed earlier.  As documents 
are deleted the numbers of other, higher documents shift downwards, but 
the order of document numbers always represents the order that documents 
were added to the index.
