This is what I thought.  Just wanted to get confirmation.

Unfortunately, re-indexing is not something that can be done easily in
the project I am on.  Hence, upgrading Lucene always has to be
considered carefully.

The problem is also further compounded by some organizations that want
to customize how there data gets indexed, with a single application then
having to be able to search across the normal and customized indexes.

Thanks for the response,
