> When combining an unbounded Lucene / Solr score with a vector score its 
> difficult or impossible to balance the two components by simply adjusting the 
> weight of the rerank score. 
> This ticket will add Min/Max scaling of both the main query scores and ReRank 
> scores to the ReRanker to support the hybrid ranking function.
