Google and we're not interested in handling millions of requests on 8
billion-document big database. Therefore no replication is needed. And
even if we had such code in place, it would be useless to almost any
our customer, since people are not ready to invest so much money into

And additionally, using Lucene with Firebird requires some fixes for
BLOB handling (implement seek for temporary blobs). The C++ port of
Lucene is not yet complete and I doubt it will ever be completed -
more likely is that gcj-compiled library will be used instead. I have
little experience with OpenFTS but their API was quite similar to Lucene.
But the worst thing are the resources. We don't have them and
therefore this feature is not yet implemented. I had a running
implementation of Firebird-based Directory for Lucene that uses BLOBs
for storage for more than 2 years and have pretty good idea how to
merge Lucene with FB. But I have no time to do it myself. If you're
interested in doing this job, contact me privately and we can discuss
