Query for term frequency

[Giulio Cesare Solaroli <sl...@ibn-italy.com>]

Hi,

we are using Lucene quite successfully. Our users are so happy with the 
performance of Lucene that they are starting making strange requests.

One of our users would like to find all documents where a given term is 
present more than a given amount of times.

As I understand Lucene (I really do understand it very poorly) this 
information should be available on the index, but I haven't found a way 
to query it within a search statement.

Did I miss something, or this in not possible to achieve with the 
current version of Lucene?

In the first case, is there anybody willing to point me to the right 
way of doing it?
If the second option is true, is there anybody already working on this?

Thanks for your time.

Regards,

Giulio Cesare Solaroli

Thanks for your reply.

Could you give me any suggestion on the best way to handle this problem?
Is it feasible to add this feature to the current Lucene architecture?

This is not supported by the existing query classes.
