Ckuangf opened a new issue, #1900:
URL: https://github.com/apache/incubator-hugegraph/issues/1900

   ### Bug Type (问题类型)
   
   gremlin (结果不合预期)
   
   ### Before submit
   
   - [X] 我已经确认现有的 [Issues](https://github.com/hugegraph/hugegraph/issues) 与 
[FAQ](https://hugegraph.github.io/hugegraph-doc/guides/faq.html) 中没有相同 / 重复问题
   
   ### Environment (环境信息)
   
   - Server Version: v0.11.x
   - Backend: RocksDB x nodes, HDD or SSD 
   - OS: xx CPUs, xx G RAM, Centos 7.x 
   - Data Size:  xx vertices, xx edges <!-- (like 1000W 点, 9000W 边) -->
   
   
   ### Expected & Actual behavior (期望与实际表现)
   
   
   实际上在一度查询时正常，二度查询时只能查出来单条路径：
   使用数据 huge中构造的点边数据如下：

   二度查询时，只能查询出来第二条路径：

   一度查询时,可以查询出来路径一和路径二

   期望可以正常查询出2条路径
   
   实际上通过gremliny验证gremlin语句时：
   一度查询：
   
![image](https://user-images.githubusercontent.com/31173360/173265806-c5df6ab3-e7cc-4642-bf8c-7b7e21f3c1e6.png)
   二度查询 两条结果正常查询出来：
   
![image](https://user-images.githubusercontent.com/31173360/173265920-229fa87d-5cc1-4599-841a-6ecb58c68577.png)
   
   gremliny地址：
   https://gremlify.com/ida02brvl5/1
   gremliny 构造数据：
   g.addV('Vertex').as('1').
     addV('Vertex').as('2').
     addV('Vertex').as('3').
     addV('Vertex').as('4').
     addE('child').from('1').to('2').addE('child').
     from('2').to('3').addE('child').from('4').
     to('3')
   查询语句：
   
g.V(2853).repeat(inE("child").outV().simplePath()).until(or(inE().count().is(0),loops().is(eq(2)))).path()
   
   
   任意类似的点边关系在huge中查询结果一致，二度查询时均会缺失只有一度结果那条路径
