bulk close 1.12.0
> Let similarity search rerank use distance as exact score

> Project: Jackrabbit Oak

> Components: lucene
> Reporter: Tommaso Teofili
> Assignee: Tommaso Teofili
> Priority: Major
> Fix For: 1.12.0, 1.10.2

>
> Currently the reranking algorithm for feature vector similarity search uses
> an additive scoring mechanism so that the final score is the sum of the
> original LSH query and the query - document feature vector distance. It turns
> out that since LSH is supposed to approximate the fv distance it'd be more
> effective to just use the exact distance as the final score instead of
> performing the mentioned sum.
