> Project: TinkerPop

> Components: process

> Reporter: Yuancheng
> Priority: Major

> Here are two queries translated from equivalent cypher queries:
> (1)
> {code:java}
> MATCH (cccccccc:A)-[]-(hketwcbf:B)<-[*1..2]-(ahdnqvvl)<-[*1..2]-(cccccccc:A)
> RETURN count(hketwcbf) {code}
> {code:java}
> g.V().as('cccccccc').hasLabel('A').emit(__.loops().is(gte(1))).repeat(__.outE().inV()).times(2).emit(__.loops().is(gte(1))).repeat(__.outE().inV()).times(2).as('hketwcbf').hasLabel('B').bothE().dedup().by(__.path()).otherV().as('test').where(__.select('test').where(eq('cccccccc'))).select('hketwcbf').count()
> // Result: 2263{code}
> (2)
> {code:java}
> MATCH (cccccccc:A)-[*1..2]->(ahdnqvvl)-[*1..2]->(hketwcbf:B)-[]-(cccccccc:A)
> RETURN count(hketwcbf){code}
> {code:java}
