Have a look at the API
http://jakarta.apache.org/lucene/docs/api/
For example, the Hits object has a score
see: org.apache.lucene.search.Hits (score)
And the IndexReader allows you to get num docs in the index and term data, etc.
see: org.apache.lucene.index.IndexReader (numDocs, docFreq)

Subject: Ask something about lucene
Deal all,
I am a new comer into this lucene e-mail list. I am doing research on
distributed information retrieval so I would like to have a few different
systems. I run the simple demo of lucene, it does not seem to statisfy all
my requirements.
I hope for those documents in the result, there is a score for each of them
to indicate the possible relevance of the document to the given query.
some other questions are: does the index include any statistics of the
collection? For example, how many documents in the collection have been
indexed? what is the frequency of a particular term?
Generally speaking, I would like to have a system that can run queries as in
TREC conference. If lucene does not work like that, then is it possible
forme to make lucene to become such a system with modest efforts? Or anyone
has done something on that?
Especially, to those of you have inside understanging of lucene, please help
me. Thanks a lot.
