Hibernate Search (formerly known as Hibernate Lucene) is not designed to use Lucene as the primary and only backend. It is designed to complement a database. I don't really like the idea actually: I'm much comfortable with having my data in a relational DB :)

So this product will not help for you request.

Perhaps this reference
http://www.mail-archive.com/[EMAIL PROTECTED]/ msg062
60.html will give you some help. It's about Hibernate Lucene
integration.

Thanks, interesting. Do you know more about this? Was the ORM implemented? Does Hibernate have some sort of built in transaction log it could store on the side?

They don't seem to talk that much about what might go wrong with a directoy though. That is my big concern. I guess my subject was a bit missleading. Up until now I have been able to rebuild the index from a database or something if it dies on me due to bad code, hardware failure or what ever reason. I can't do that if the index was the only place I saved the data.

Perhaps it is a backup-solution I'm looking for. Maybe there are some expensive or sensitive things I need to watch out a bit extra when calling as, or something. I don't know. That is why I'm asking.

Subject: Lucene as primary object storage

Until recently I have only used Lucene as an index. I'm very
interested to hear what you people have to say about using Lucene as
the primary and only persistance layer in an application.

I would feel much safer if I had a transactionlog for crash recovery.
So I might get me one of those. Are there more things I should worry
about?
