我有一个看似正确配置的空间图层和索引,并且可以使用findGeometriesWithinDistance REST API调用成功查询节点.
POST /db/data/ext/SpatialPlugin/graphdb/findGeometriesWithinDistance {"layer":"geom","pointX":15.0,"pointY":60.0,"distanceInKm":100.0}
但是,当使用cypher进行查询时,我没有得到任何结果(我试过没有运气就颠倒了60.0和15.0的顺序):
START n=node:geom('withinDistance:[60.0, 15.0, 500.0]') return n;
Cyper返回:
==> +---+
==> | n |
==> +---+
==> +---+
==> 0 row

==> 13 ms
