An exception is thrown when executing the Cypher query "MATCH (n0) OPTIONAL MATCH (n0)-->(n1) RETURN *"

[abc123000111]

Describe the bug
When I used the Java client to execute the following Cypher query:

MATCH (n0) OPTIONAL MATCH (n0)-->(n1) RETURN *

An exception occurred:

com.alipay.tugraph.TuGraphRpcException: CypherException: Function not implemented yet: AddClause at :211

Expected behavior
No error occurs because this Cypher query is syntactically correct and valid and the doc says that "OPTIONAL MATCH is supported" .

Environment:

• OS: MacOS 10.15.7
• Version: TuGraph 3.3.0 docker, Java client

tugraph currently does not support this Cypher query, you can use:
MATCH (n0) WITH n0 OPTIONAL MATCH (n0)-->(n1) RETURN *
