查询结果-查看$var4
通过$var4进行最终查询

你的 vid 是不是 int 报错是说你的 vid 需要是个 string。我大概明白了，上面大兄弟是 v1.x 版本的，那时候 vid 只能是 int，所以需要做 hash 生成 vid。
如果你要用一样的话，直接
$var1=go from "V1" over E1 yield E1._dst as dst;
$var2=go from "V2" over E2 yield E2._dst as dst;
$var3=yield $var1.dst as dst union yield $var2.dst;
go from $var3.dst over E3 reversely
$var1=go from “V1” over E1 yield E1._dst as dst;
$var2=go from $var1.dst over E2 yield E2._dst as dst;
$var3=yield $var1.dst as dst union yield $var2.dst;
go from $var3.dst over E3 reversely
$var2 的 from id是引用$var1的结果，执行就报这个错：-1005:NULL', the srcs should be type of STRING, but wasNULL’
