### Description
Hi, I have a question when using hnsw int4.
I have built an index using Lucene99HnswScalarQuantizedVectorsFormat bits=4
param. But I don't know how to use it in search.
I have code below to load index:
Directory directory = FSDirectory.open(indexPath);
IndexReader reader = DirectoryReader.open(directory);
I don't know how to pass bits=4 param when loading index or when searching,
the code runs with default value bits=7 and the results are not correct.
So how to use int4 in code when loading or searching? Thanks for your answer
