* Have one score definition for cosinesimilarity Currently we have different score calculation for cosine similarity, for ex: script score, approximate search, exact search has diffent formula to convert distance to cosine similarity that is aligned with OpenSearch score. To keep it consistent, we will be using one defintion which is used by Lucene as standard definition for cosine similarity for all search types.
