Review Comment: Hi, thanks for working on it. I was not involved in the recent format changes in the vector values, but I don't think Lucene 9.1 can read `Lucene90HnswVectorsFormat` as @alessandrobenedetti explained - I haven't tried yet, I'll check it this week and report my observation here. I noticed we don't have a MIGRATE entry in Lucene for the file format change. I think it'd be better to have some notes on reindexing to avoid unnecessary confusion. -- This is an automated message from the Apache Git Service.
