------------------------------------
Summary: Bound values of boosts
Key: LUCENE-8016
URL: https://issues.apache.org/jira/browse/LUCENE-8016
Project: Lucene - Core
Issue Type: Task
Reporter: Adrien Grand
Priority: Minor
Fix For: master (8.0)
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?
