> 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 as:
> {noformat}
> public static Document nearest(IndexReader r, String field, double lat,
> double lon) throws IOException
> {noformat}
> I only implemented the 1 nearest neighbor for starters ... I think we can
> easily generalize this in the future to K nearest.
> 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.
> I don't think this should go into 6.0.0, but should go into 6.1: it's a new
> feature, and we need to wrap up and ship 6.0.0 already ;)
