我有以下类型的查询:
MATCH (u1:User{name:"user_name"}), (s1:Statement), s1-[:BY]->u1
WITH DISTINCT s1,u1
MATCH (s2:Statement), s2-[:BY]->u1,
p=s1<-[:OF]-c-[:OF]->s2
WHERE s1 <> s2
WITH collect(p) AS coll, count(p) AS paths, s1, s2
RETURN s1,s2,paths,coll
ORDER BY paths DESC
LIMIT 2;
现在它返回coll
变量中所有路径p的列表。我希望它只列出节点c
。如何做到这一点?
也许查询不对,在这种情况下,我要做的是
1)查找用户发表的所有陈述;
2)找到连接这两个语句的节点;
3)返回那些连接它们的节点最多的语句ORDER BY DESC,包括连接它们的实际节点的名称。
谢谢!

我目前无法测试,但您可以尝试类似
的内容MATCH (u:User {name:"user_name"})<-[:BY]-(s1)<-[:OF]-(c)-[:OF]->(s2)-[:BY]->(u)
RETURN s1, s2, collect(c) as connections
ORDER BY length(connections) DESC
LIMIT 2
