> Key: LUCENE-9645
> URL: https://issues.apache.org/jira/browse/LUCENE-9645
> Project: Lucene - Core
> Issue Type: Improvement
> Components: core/other
> Affects Versions: 8.6.2
> Reporter: kkewwei
> Priority: Major
>
> In BKDReader$IndexTree, the private final variable negativeDeltas seems
> useless. It will be only used in BKDReader.readNodeData(), we use
> negativeDeltas[level * numIndexDims + splitDim] to check whether the current
> nod is left or right, but it can be replaced by isLeft which is the function
> parameter.
