Environment:
在阿里云计算巢购买的 tugraph

Describe the bug

执行下面的cypher会报错，在neo4j是正常执行的

MATCH (k:K)
WHERE k.Id IN ['1']
OPTIONAL MATCH path1 = (k)-[*1..3]-(e:E)
OPTIONAL MATCH path2 =(k)-[*1..3]-(m:M)
OPTIONAL MATCH path3 =(k)-[*1..3]-(l:L)
RETURN path1,path2,path3

我们目前还未支持多个match并列，您可以尝试一下这样的写法

MATCH (k:K)
WHERE k.Id IN ['1']
WITH k as a
OPTIONAL MATCH path = (a)-[*1..3]-(e:E)
return path
UNION ALL
MATCH (k:K)
WHERE k.Id IN ['1']
WITH k as a
OPTIONAL MATCH path =(a)-[*1..3]-(m:M)
return path
UNION ALL
MATCH (k:K)
WHERE k.Id IN ['1']
WITH k as a
OPTIONAL MATCH path =(a)-[*1..3]-(l:L)
RETURN path
