Hi Alex
Just to make sure I understand better what the additions are about

There were a couple additions recently merged into lucene but not yet
released:
- A first-class vector codec
do you mean the classes inside
https://github.com/apache/lucene/tree/main/lucene/core/src/java/org/apache/lucene/codecs/lucene90
and in particular
Lucene90HnswVectorFormat.java Lucene90HnswVectorReader.java
Lucene90HnswVectorWriter.java
?
- An implementation of HNSW for approximate nearest neighbor search
the HNSW implementation at
https://github.com/apache/lucene/tree/main/lucene/core/src/java/org/apache/lucene/util/hnsw
is similar to
https://opendistro.github.io/for-elasticsearch/blog/odfe-updates/2020/04/Building-k-Nearest-Neighbor-(k-NN)-Similarity-Search-Engine-with-Elasticsearch/
?
They are however available in the snapshot releases. I started on a small
project to get the HNSW implementation into the ann-benchmarks project, but
had to set it aside.
Is there still something missing? Or what would be the next steps?
Thanks
Michael
Here's the code:
https://github.com/alexklibisz/ann-benchmarks-lucene. There are some test
suites that index and search Glove vectors. My first impression was that
indexing seems surprisingly slow, but it's entirely possible I'm doing
something wrong.

Hi
I recently found the following articles re Lucene/Solr and BERT
https://dmitry-kan.medium.com/neural-search-with-bert-and-solr-ea5ead060b28
https://medium.com/swlh/fun-with-apache-lucene-and-bert-embeddings-c2c496baa559
and would like to ask whether there might be more recent developments
within the Lucene/Solr community re BERT integration?
Also how these developments relate to
https://sbert.net/
?
Thanks very much for your insights!
Michael
