URL: https://github.com/apache/incubator-hugegraph/issues/2121

   ### 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: v0.12.0
   - Backend: in memory 
   - 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)
   
   When I execute the query `g.E().inV().inE('teach')` without HugeVertexStepStrategy, it returns an empty set, instead of the expected result set. However, we can get the correct result when executing the query `g.E().inV()` without HugeVertexStepStrategy.
   
   ```
   gremlin> g.withoutStrategies(HugeVertexStepStrategy).E().inV().inE('teach')
   // actual result
   {}
   // expected result
   ==>[id:L693854165436203010>2>>L693854165436203008,label:teach,type:edge,outV:693854165436203010,outVLabel:person,inV:693854165436203008,inVLabel:person,properties:[year:2]]
   ==>[id:L693854165436203010>2>>L693854165436203008,label:teach,type:edge,outV:693854165436203010,outVLabel:person,inV:693854165436203008,inVLabel:person,properties:[year:2]]
   ```
   
   
   The graph is created as following.
   
   ```
   hugegraph.schema().propertyKey("age").asInt().ifNotExist().create();
   hugegraph.schema().propertyKey("year").asInt().ifNotExist().create();
   
   // vertex
   hugegraph.schema().vertexLabel("person").properties("age").nullableKeys("age").create();
   hugegraph.schema().indexLabel("personbyage").onV("person").by("age").shard().ifNotExist().create();
   
   // edge
   hugegraph.schema().edgeLabel("knows").sourceLabel("person").targetLabel("person").properties("year").ifNotExist().create();
   hugegraph.schema().edgeLabel("teach").sourceLabel("person").targetLabel("person").properties("year").ifNotExist().create();
   hugegraph.schema().indexLabel("knowsbyperson").onE("knows").by("year").shard().ifNotExist().create();
   hugegraph.schema().indexLabel("teachbyperson").onE("teach").by("year").shard().ifNotExist().create();
   
   GraphManager graph = connection.getHugespecial().graph();
   
    /** create graph data */
   Vertex person1 = new Vertex("person").property("age", 12);
   Vertex person2 = new Vertex("person").property("age", 23);
   Vertex person3 = new Vertex("person").property("age", 24);
   
   graph.addVertices(Arrays.asList(person1, person2, person3));
   
   Edge edge1 = new Edge("knows").source(person2).target(person1).property("year", 3);
   Edge edge2 = new Edge("teach").source(person3).target(person1).property("year", 2);
   graph.addEdges(Arrays.asList(edge1, edge2));
   ```
