We shouldn't ever return negative scores from vector similarity functions. Given vector panama and nearly antipodal float[] vectors, it is possible that cosine and (normalized) dot-product become slightly negative due to compounding floating point errors. Since we don't want to make panama vector incredibly slow, we stick to float32 operations for now, and just snap to `0` if the score is negative after our correction. closes: https://github.com/apache/lucene/issues/12700 -- This is an automated message from the Apache Git Service.
