Index-time boosts are a very expert feature whose behaviour is tight to the
Similarity impl. Additionally users have often be confused by the poor
precision due to the fact that we encode values on a single byte. But now we
have doc values that allow you to encode any values the way you want with as
much precision as you need so maybe we should deprecate index-time boosts and
recommend to encode index-time scoring factors into doc values fields instead.
