> 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. 
> What's needed is the ability to min/max scale the Lucene / Solr score between a specific range so that the rerank score can be weighted against it reliably.
> This ticket will add min/max scaling parameters to the reranker. The min/max scaling will be applied to the scores of all the topDocs prior to combining with the rerank score.
