Sounds quite interesting. You might be interested in http://wiki.apache.org/solr/TermVectorComponent
. If anything, the Solr code will show you how to do get the
information out of the Lucene index.

just a test to see if this hypothesis is working or not.

Assuming you want to handle the vectors yourself, as opposed to
relying on the fact that Lucene itself implements the VSM, you
should index your documents with TermVector.YES. That will give you
the term freq on a per doc basis, but you will have to use the
TermEnum to get the Doc Freq. All and all, this is not going to be
very efficient for you, but you should be able to build up a matrix
from it.
What is the problem you are trying to solve?

Hello all,
I'm trying to implement a vector space model using lucene. I need
to have a file (or on memory) with TF/IDF weight of each term in
each document. (in fact that is a matrix with documents presented
as vectors, in which the elements of each vector is the TF
weight ...)
Please Please help me on this
contact me if you need any further info via andykan1...@yahoo.com
Many Many thanks
