Hi,

I actually work on Java/J2ee project. I have to develop a fulltext seach and a versionning functionnalities.
I use Hibernate Search for the fulltext search, and Hibernate Envers for the versionning.

All is working fine, but I have a new need : when I search with hibernate, I want to search over my indexed entities and theirs previous versions.
Is it possible ? If yes, how is it possible ?

No, we never implemented versioned indexes so it's not very simple.

Still you could contribute the feature: Lucene indexes are generational so since we already associated a set of index updates to a single transaction, you would need just to:
- make sure older index generations are not cleaned up automatically
- somwhere track which Envers transactions version has to match to each index generation
- make sure the queries are run on the specific index generation rather than the standard index

Thank you for your answer Sanne.

But I don't understand the differents steps... Is it possible to do that by extending Envers classes in my project ? Or do I need to modify the Envers framework ?
