Your problem is out of my experience, so all I can suggest is that you
search the list archive. I know the idea of faceted searching has been
discussed by people with waaay more experience in that realm than I have
and, as I remember, there were some links provided....

I just searched for 'faceted' on the e-mails I've seen since I subscribed to
the list, and there are certainly discussions out there...

Thanks, I have got it working now. But I think it is not a viable
solution either. These are the problems that I see:
- the number of segments will probably increase too fast, requiring
optimizations regularly.
- Given the size of the external data, making it consistent with the
Lucene index will, in the worst case, require processing and writing to
disk of hundreds of megabytes.

The biggest problem is of course the combination of them: having to
process too much data too may times.
