Adrien Grand updated LUCENE-8016:
---------------------------------
Description:
We allow any boosts to be passed down to similarities, eg. via {{BoostQuery}}.
This is a bit trappy since it means that you can make scores rounded down to 0
and/or slow to compute (because of subnormal floats) by using tiny boosts, or
infinite scores if you pass boosts that are too close to the float max value.
I would like to restrict boosts to be either +0 or between 2 ^-10^ and 2 ^10^ .
Any objections?
