-------------------------------------
Summary: Add min/max scale params to reranker
Key: SOLR-16827
URL: https://issues.apache.org/jira/browse/SOLR-16827
Project: Solr
Issue Type: Improvement
Security Level: Public (Default Security Level. Issues are Public)
Reporter: Joel Bernstein
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 with rerank score.
