How to returns the stored fields of the Document in this index of Nutch?

Hello everyone: 
in order to returns the stored fields of the Document in this index. 

if index is Lucene2.0 then using: 
IndexReader reader = IndexReader.open(INDEX_STORE_PATH); 
for(int i=0;i<reader.numDocs();i++){ 
                System.out.println(reader.document(i)); 
}

Hey,

Hits hits = bean.search(query, 10);
Hit[] show = hits.getHits(0, length);
HitDetails[] details = bean.getDetails(show);

Each detail array element would have field value accessible by field 
name or index

Above snippet is from NutchBean 's main class and similar code is in 
search.jsp file
