----------------------------------
Summary: Add N-dimensional FloatPoint K-nearest-neighbor
implementation
Key: LUCENE-7974
URL: https://issues.apache.org/jira/browse/LUCENE-7974
Project: Lucene - Core
Issue Type: New Feature
Components: modules/sandbox
Reporter: Steve Rowe
Assignee: Steve Rowe
Priority: Minor
>From LUCENE-7069:
{quote}
KD trees (used by Lucene's new dimensional points) excel at finding "nearest
neighbors" to a given query point ... I think we should add this to Lucene's
sandbox
[...]
It could also be generalized to more than 2 dimensions, but for now I'm making
the class package private in sandbox for just the geo2d (lat/lon) use case.

This issue is to generalize {{LatLonPoint.nearest()}} to more than 2 dimensions.
