How large of a subset are you talking?
You might look at the FitleredTermEnum class, but you will probably
have to do some work on it to extend it to what you want
If you are talking a smallish subset (say, at most a couple hundred
docs), then you could store Term Vectors and use the TermVectorMapper,
I suspect.

Hello everyone. I've been fiddeling with the idea of retrieving the
top terms from a subset of the index (i.e. top terms from the
documents retrieved by a given search). This could for instance be
useful to identify top ranking terms in a given datespan etc.
It would be something like getting the top 50 terms (like you can do
with luke) but instead of doing it for the full index, I would like
to do the same procedure after applying a filter or a query. Don't
know if this is a bad explaination or wheter it makes any sense at
all...
So, I really want to avoid iterating over all results (obviously),
so my question is really if there is a prefered approach for doing
such analysis / has this been done in a good way before?
Thanks for any help!
Best regards,
Aleksander
