Elastic relies on lucene's implementation of HNSW. Per [GitHub - erikbern/ann-benchmarks: Benchmarks of approximate nearest neighbor libraries in Python](https://github.com/erikbern/ann-benchmarks), there are several fast HNSW implementations such as nmslib. Is there any plan to support other HSNW engines?
