> 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.
