I'm trying to reduce the memory requirement of my application that has ~40

What would I lose by omitting norms? The ability to boost individual fields
as they are added to the index? Anything else?
Length normalization of the field. Full-text matches on shorter
fields score higher because the match is seen as more specific. You
loose that if you omit norms. That's typically OK for short fields
like "title" anyway, and fields that aren't full-text (like dates,
numbers, etc).
