Hi every body

I know it may seem stupid, but I'm in the middle of a research and I need a piece of code in lucene to give me a weight matrix of a text collection and a given query:

W i,j = (f i,j)x(idf i)
AND    for the query: 
W i,q = (0.5 + (0.5xfreq i,q)/Max(freq i,q))x (idf i )

where:

f i,j = Normilize frequency = freq i,j / Max(freq j)
freq i,j = frequency of (k i) in document j (d j)
idf i= log(N/(n i))                      idf= Inverse Document Frequency
N = total number of documents in the collection
n i = number of documents which has the TERM i (k i)

could any body help?
Many thanks in advance
best wishes to all

Asking people to write some code for you isn't typically an effective
strategy to get assistance.  You're more likely to get assistance from the
community if you provide some indication that you've at least looked at
the Lucene APIs and made some attempt at investigating a solution for
yourself -- ideally br asking specific questions about things you've
tried that haven't worked for you...

That said: if you have no experience and/or interest in java code, and
just want someone to write it for you, there are a list of
people/companies that provide services for hire...
