I'm slightly confused. I thought MG did truncation too.

2nd question: Is Lucene being added so that there can be incremental adds
to the index? And I'm kind of curious how Lucene does this. Partly because
I was thinking that a Greenstone collection could effect an incremental
add if the new documents were indexed separately and then the retrieval
system was told to look in both indexes, kind of like cross-collection
searches, just with the second collection being the new documents.
