Thanks, Jeff.

I have only done basic testing, so not completely sure on your 
question.  However, one trade off is definitely in disk space.  As far 
as searching, I don't think there should be any impact b/c you get the 
vector separate from a search via the IndexReader.  Perhaps, the 
compound file format might effect it as the file will be larger, but 
that is only speculation.  I haven't noticed any performance impact 
other than the increase in disk space needed.
