[GitHub] [lucene] jtibshirani opened a new pull request #400: LUCENE-10146: Add note that dot product is preferred over cosine
jtibshirani opened a new pull request #400:
URL: https://github.com/apache/lucene/pull/400
While VectorSimilarityFunction#COSINE is helpful when you need to preserve the
original vectors, it is significantly slower than DOT_PRODUCT. This commit adds
javadocs to COSINE explaining that dot product is the fastest option.
