我想通过match 来代替部分find path不支持where查询的场景，没想到性能有点问题，查询的时候直接down掉一台机器
执行如下语句没有问题：
FIND SHORTEST PATH FROM 362234 to 699108 OVER word_word upto 2 steps ;
执行如下语句就直接挂掉一台机器：
MATCH p=(v) -[e1:word_word]->(v1)-[e2:word_word]->(v2) WHERE id(v)== 362234 and id(v1) == 963 and id(v2) == 699108 RETURN p;
explain结果看不懂
explain MATCH p=(v) -[e1:word_word]->(v1)-[e2:word_word]->(v2) WHERE id(v)== 362234 and id(v1) == 963 and id(v2) == 699108 RETURN p;
Execution succeeded (time spent 474/44489 us)
Execution Plan (optimize time 78 us)
