ApacheAGE给出了通过可变数量的中间节点获得从一个顶点到另一个顶点的路径的方法。

(u)-[*3..5]->(v)

我在ApacheAGE中尝试了以下查询，它确实给予了所需的结果。

test=# SELECT * from cypher('cities', $$
MATCH p = (d:CITY {name:"Delhi"})-[:WAY_TO*..2]-(r:TOWN {name:"Rishikesh"})
RETURN relationships(p)
$$) as (a agtype);
                                                                                                                                              a

但是，AGE查看器中的相同查询不会产生任何输出。

我意识到这可能是因为没有为中间节点声明agtype变量，但是，我想知道是否有一种变通方法可以获得所需的结果。
