iprithv opened a new issue, #16064: URL: https://github.com/apache/lucene/issues/16064
### Description right now, FaissKnnVectorsFormat only supports DOT_PRODUCT and EUCLIDEAN. If we try to use COSINE, it fails at runtime with an UnsupportedOperationException. since cosine similarity is commonly used, and Lucene already supports it we should add it. also, the base test suite (BaseKnnVectorsFormatTestCase) includes cosine, so Faiss isn’t really on par with other formats like HNSW yet. ### Gradle command to reproduce _No response_ -- This is an automated message from the Apache Git Service.
