Subject Re: Attached proposed modifications to Lucene 2.0 to support Field.Store.Encrypted

That is a valid consideration Doron, which brings the discussion back to the
difference between encrypton and security. I believe that security is an end
application responsability, not Lucene's. For instance, is it possible to
write the end application so that those stats are hidden from or
inaccessible to users?
