> Key: SOLR-16990
> URL: https://issues.apache.org/jira/browse/SOLR-16990
> Project: Solr
> Issue Type: New Feature
> Security Level: Public(Default Security Level. Issues are Public)
> Components: reranker
> Reporter: Joel Bernstein
> Assignee: Joel Bernstein
> Priority: Major
>
> Currently the Lucene vector scores are scaled to avoid negative values. There
> are times when it is preferred to provide the unscaled vector scores with
> "clamping" to avoid negative scores. The clamping will simply set a floor for
> the vector score so it does not go below zero.
> Two parameters will be added to the reRanker to support unpacking and
> clamping the raw scores.
> reRankMainRV=<float floor> : This will unpack the main query vector score and
> clamp at the specified value.
> reRankRV=<float floor> : This will do the same for the reRank query vector
> score.
> The RV stands for "raw vector" score.
