> There is a minor looping bug when generating Full KNN results for comparison
> with HNSW in KnnGraphTester. Basically, the result in [this
> line|https://github.com/apache/lucene-solr/blob/a53e8e722884e5655206292590da67bb71efc34d/lucene/core/src/test/org/apache/lucene/util/hnsw/KnnGraphTester.java#L551]
> should be calculated after the while loop finishes.
> Without this fix, vector files with ~2GB will work fine but if size of files
> are more than that, it may cause incorrect Full KNN results.
