There is an API for it:

http://hudson.zones.apache.org/hudson/job/Lucene-trunk/javadoc/org/apache/lucene/index/IndexReader.html#document(int,%20org.apache.lucene.document.FieldSelector)

"Get the Document at the nth position. The FieldSelector may be used to
determine what Fields to load and how they should be loaded."
