Get TF-IDF from index?

[Jack <jl...@gmail.com>]

I have only used the basic functionality of solr - post and query,
which works great.

I wonder if it's possible to get more information from the index. For
example, I'd like to get the TF-IDF score of a given term, or get a
list of terms sorted by TF-IDF, not from a given document, but from
the whole corpus, or, simply to enumerate all indexed terms.

Maybe solor doesn't expose this data, but I can use Lucene jar to get
them? Since I am not familiar with Lucene, either, any pointer is
helpful.

Thanks,
jack

Have a look at the LukeRequestHandler (I think it is only on trunk).
