-----------------------------------------

Interesting idea.
I didn't look at the API differences, but it should be doable - however it is my understanding that it's not maintained anymore, so I wonder if it would make sense.
As an alternative we could re-implement something similar to maintain it properly but I've always been skeptical about how good it fits in a database, especially performancewise: I might be wrong but it doesn't feel like the right tool for the job.

Did you consider using the Infinispan Lucene Directory instead? It would cache as much as possible in memory, but you can still enable a cachestore to persist the index in a database so that you can always kill the nodes without losing the index. This is how I use it myself most of the time, but it takes some configuration files. I guess we could simplify the configuration of it or at least provide more examples.

> It would be great if there were a database backed Luncene Directory and DirectoryProvider. This would be roughly similar to what Compass provided with their JdbcDirectory class. Unfortunately due to Lucene API differences, it's not easy to drop the Compass JdbcDirectory into Hibernate Search.
