The indexation part of Hibernate Search relies on Java Persistence
API to triggers the index update transparently. Otherwise you can
trigger it manually to follow the crawling approach (not transparent).
Event driven vs crawling driven index update have both use cases, I
would not say that one is really more generic than the other.
Anyway, Krishna, if you use Lucene 2.1, I like the new
IndexWriter.updateDocument APIs, it's really neat when you have one
of the term representing your unique id (in your case that would be
table name + id). I don't fit into those requirements but it would
have saved me a lot of time if I did :D

Does it mandate you to pass data through Hibernate? This seems very
similar to Compass' approach.
I believe a more generic approach is to compare what's already indexed
with what's changed or deleted, so you can use any framework to work
with Lucene. And simply selecting the data and creating the index can
avoid some specific framework limitation and easier to scale. Also,
re-indexing will also be easier.
DBSight tracks changes through simple SQLs, hard-deleted or
soft-deleted content, and do it very efficiently even for large number
of documents.
