Yonik Seeley commented on LUCENE-582:
-------------------------------------

Any fallback strategy should attempt to score the same way.  If it doesn't it's 
brittle and will lead to surprises (e.g. when I add one more document to my 
index, I don't want scoring to radically change).

I did some work in the direction of using a scorer with a byte per document to 
keep track of scores:

A variation of norms 8 bit float is already checked into lucene... see 
lucene.util.SmallFloat.
