Hello,

I try to use Lucene to make some experiments with the distribution of words

in documents. Using the TermPositionVector, one can compute some statistics

about word positions (mean, standard deviation, etc.).

It is possible to store such statistical values directly in the Lucene

index?

For example, I want to save the statistical values of each Term by the index

process, and get them later in query time.

Term => <docNum, freq, <X1, X2, ... ,Xn> >

Where <X1, X2, ... ,Xn> are some statistical values about the Term position

in docNum.

Should I modify the classes: IndexWriter.java and IndexReader.java?

Thank You
