Term frequencies within a search

[Robert Young <ro...@roryoung.co.uk>]

Hi,
I would like to perform a query and then get a summary of the term
frequencies of the result. Is this possible?

Thanks
Rob

For all the docs, and in fact, I think it might be the document frequency.
Basically I need to be able to do a query and get a list of terms with how
many documents in the result set contain that term. I'm not so worried about
how often the term appears in each document.

Thanks
Rob

This is often requested, but Lucene doesn't make it easy.  I'd love
for someone to come up and build this feature :)

Do you need term freqs for just the top N that were collected?  Or for
all docs that matched the query?
