withinDistance
이 Cypher에서 올바르게 작동하지 못합니다.neo4j spatial cypher withinDistance 문제
지형을 추가하고 지형을 추가하고 공간 REST findGeometriesWithinDistance
을 사용하여 색인을 호출하고 쿼리 할 수 있습니다.

단 I은 사이퍼를 이용 withinDistance
를 호출 할 때, 예를 들어
POST /db/data/cypher {"query":"START n=node:yada('withinDistance:[-87.845556,42.582222,10.0]') RETURN n"}
나는이 동작을 시작하지만 최근 뭔가 것 같다 때 나는 확실하지 않다 다시

얻을. 내가 여기서 뭔가 잘못하고있는거야?
감사합니다, 폴

대소 문자를'withinDistance'에서'WITHINDISTANCE'으로 변경하면 더 좋아집니다. – ulkas
아니요, 소스 코드 (https://github.com/neo4j/spatial/blob/master/src/main/java/org/neo4j/gis/spatial/indexprovider/LayerNodeIndex.java), 라인에 오타가 있다고 생각합니다. 278에 "% s, % S 및 % s 만 구현되었습니다." – pauldzy
