Jan Høydahl commented on LUCENE-6819:
-------------------------------------
If removal is plannend for 7.0, we must make sure at least one minor 6.x
release contains deprecation and documentation heads-up, also for Solr, else
I'll be -1 on committing this.

> 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.
