> Since Lucene90 didn't support sparse vector values, I am not sure this is strictly necessary. But I can understand it from a consistency standpoint. After reflection, I don't think this is true. We always supported sparse vector indexes - I don't see how we could have avoided it, really. It seems to me this bug was introduced [here](https://github.com/apache/lucene/commit/a65cf8960a1057d98126256d1610292ad5c8f1b3#diff-b75a9bbd95dd9708267528a08f3d0b1093f74feb179f03f16f8dfb1857930077L271) and it was released as part of 9.8, meaning that releases 9.8 and later in the 9.x series will be able to read indexes produced in 9.0 but will give meaningless results for HNSW searches over those indexes.
