> Apache Lucene 10.x supports better binary quantisation.
> Implemented in the org.apache.lucene.codecs.lucene102.Lucene102HnswBinaryQuantizedVectorsFormat.
> The idea is to expose it in Apache Solr.
> This contribution may follow the same style as the scalar quantisation contribution, adding a new field type for the binary quantisation.
