Hello,
I'm a graduate student in the Information School at the University of
Washington. I'm currently in the process of developing a prototype
online IR system and I have been making use of Lucene's API. I'm just
beginning to plan out some mechanisms for query expansion and relevance

seem to find an answer to this.
I would like to present the terms that matched for each document in the

Thanks for the reply, Joshua. I'm really just beginning my studies in
IR so forgive any niavete. Please see my comments below.

Hi Rob,
One possibility might be to use the IndexReader's termDocs(Term) method
and then use the skipTo(int) method on the TermDocs object. Iterate
over your document list and then your term list for each document. Each
time skipTo puts you at the document you are looking for, you can add
Sorry... That should be:
1) iterate over your term list
2) for each term, iterate over your document list using the document
number in the skipTo() method
3) if skipTo puts you on the current document, add term to
(document,term) list

Thanks. This seems to work for stored fields (although I haven't completed
all of the steps). However, I want it to work with an indexed, but

There must be some way to do it because this information is what is being
