Description

### Description

Hi,
I was wondering if anyone has looked into implementing the link and code algorithm from FaceBook in Lucene. It seems the performance is really good based on the benchmarking results reported in the paper. There is an implementation in faiss, though for an older version of the library.

Research direction

Start by reading the linked Faiss link-and-code README and the referenced benchmarking results to understand the algorithm and its expected behavior. Determine whether Lucene has a suitable vector-search entry point, then define the implementation scope and validation criteria before proposing the feature.
