Question about applications using different versions of Lucene

Am I correct in understanding that you have two seperate applications: one

DOH!

Thanks,

Van

However the second application then tried to update the already upgraded index and messed things up. I think this may even be worse, as one of the changes since 2.0 is that write locks are now (by default) maintained in the index directory.
