Orientdb查询-查找指向顶点的所有连接

我在orientdb中有以下用例

(V= Vertex, E=Edge)
FacebookAccount(V) -> OwnedBy(E) ->Human(V) 
TwitterAccount(V) -> OwnedBy(E) ->Human(V) 

TwitterAccount(V) OR FacebookAccount(V) -> FriendOf(E) -> TwitterAccount(V) OR FacebookAccount(V)

我想看看所有的人类是如何与一个特定的人类联系在一起的。 1.我不想看到非人类所有的

facebook账户

或

twitter账户

，这应该被隐藏：

15:2

2.我不想看到

FacebookAccount

或

TwitterAccount

是一个

Human

所拥有的

而不是另一个
Human
。这些应该隐藏：
17:0、18:0、17:1

我有以下疑问：

traverse in("FriendOf"),out("FriendOf"), in("OwnedBy"),out("OwnedBy")  from #19:0 while $depth <= 10 

看起来您可能想阻止任何帐户不为任何人所有。OwnedBy作为链接可能比边缘更好，因此您可以强制使用它（并且每个帐户只强制一个所有者）。此外，如果用户和OwnedBy总是相同的，那么您可以将它们合并到一个链接中。看起来您可能希望防止任何帐户不为任何人所有。OwnedBy作为链接可能比边缘更好，因此您可以强制使用它（并且每个帐户只强制一个所有者）。此外，如果user和OwnedBy始终相同，则可以将它们合并到一个链接中。
