尝试了两种方法还是不能把两点之间的三条边一次性查出来，请问有什么办法可以实现吗？

Match 是可以的，你插入的是 player100，match 的条件是 player102 吧。

(root@nebula) [nba]> match (v) - [e:serve] - (v1) where id(v) == "Blake Griffin" and id (v1) == "Clippers" return e
+------------------------------------------------------------------------------------+
| e                                                                                  |
+------------------------------------------------------------------------------------+
| [:serve "Blake Griffin"->"Clippers" @0 {end_year: 2018, start_year: 2009}]         |
+------------------------------------------------------------------------------------+
| [:serve "Blake Griffin"->"Clippers" @3 {end_year: __NULL__, start_year: __NULL__}] |
+------------------------------------------------------------------------------------+
| [:serve "Blake Griffin"->"Clippers" @2 {end_year: 2018, start_year: __NULL__}]     |
+------------------------------------------------------------------------------------+

GO FROM “player100” OVER serve WHERE serve._rank> -1 and serve._dst==‘team204’ YIELD serve._src, serve._dst, serve._rank AS Rank;
@HarrisChu 谢谢，果然写错了，go from 也可以 。看来这个问题很简单啊
GO FROM “player100” OVER serve WHERE serve._dst==‘team204’ YIELD serve._src, serve._dst, serve._rank AS Rank;
