Subject RE: creating indexReader object

Lucene's fields are case sensitive and I think "contents" is written in
lower case by default.

Cheers,
Frank

thanx hannes, 

but i dont think i made my query clear enough.
i have created the index reader object just the way you mentioned it, but
after that when i try to do create the vectors like term frequency and
document frequency using

doc(i).get("Contents"); 

i get an only NULL

any ideas ?

cheers,
