查询节点的邻居节点，并且每种类型的邻居返回m条

• cypher
  • MATCH path =(n:实体标签)--(m) WHERE n.name='aa' with m.type as mtype,collect(path)[..m] as paths return paths;
  • MATCH(n:实体标签{name:'aa'})-[r]-(m) with m.type as tp,collect(r)[..m] as rels unwind rels as r return startNode(r),endNode(r),type(r)
• apoc 动态cypher
  • MATCH(n:实体标签{name:'aa'}) CALL apoc.path.subgraphAll(n,{relationshipFilter:NULL,labelFilter:NULL,maxLevel:1}) YIELD relationships UNWIND relationships AS r with endNode(r).type AS lab, collect(r)[..m] as rels UNWIND rels AS rel RETURN startNode(rel).name AS fromNode, endNode(rel).name AS toNode, type(rel) as relType
