For an enterprise-level application, Lucene appears too file-system and

There are good reasons why Lucene is not built on top of a RDBMS. An
inverted index is not efficiently maintained in a B-Tree, and B-Trees
are the foundation of RDBMSes.

I'd be OK with an RDBMS-based Directory implementation I could take and use.
But generally, I think the Lucene authors might like to take a step back and
consider splitting off the repository and making it more extensible and
high-level. Perhaps something like JSR-170 (Java repository API) may be a good
route to go....
If you have concrete ideas for an improvements to Lucene's Directory
interface, please propose them to the java-dev mailing list, ideally as
a patch.
Cheers,
Doug
