Okay - I guess that somewhat makes sense - you can calculate the
magnitude of the doc vectors at index time. How is that impossible with
incremental indexing though? Isn't it just expensive? Seems somewhat
expensive in the non incremental case as well - your just eating it at
index time rather than query time - though the same could be done for
incremental? The information is all there in either case.
