show additional lucene index information on Nutch's Search Page

[Feng Ji <fe...@gmail.com>]

Hi there,

I used indexer to store one additional field in lucene index,
Field.Store.YES, Field.Index.NO. (I will only add one single field, I see
the discuss about performance penalty of this)

then, I want to retrieve it from nutch's search page. I took a look of how
nutch to get explanation and seems the logic go down to lucene package.
(maybe I miss something important)

I wonder if there is a way to retrieve indexed field and show it in search
page in nutch.

thanks,

Michael

If the field is stored (i.e. indexed with Field.Store.YES), then you can 
retrieve it from HitDetails.getValue(fieldName).
