zhengyingying opened a new issue, #1981:
URL: https://github.com/apache/incubator-hugegraph/issues/1981

   ### Bug Type (问题类型)
   
   _No response_
   
   ### 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: inmemory 
   - 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)
   
   We create three vertices and expect the second query return value `2`, but it returns value `3`. 
   
   ```
   gremlin> :> hugegraph.traversal().V().sample(2)
   ==>[id:647369467348647938,label:product,type:vertex,properties:[name:product3]]
   ==>[id:647369467348647937,label:product,type:vertex,properties:[name:product2,price:4.5688]]
   gremlin> :> hugegraph.traversal().V().sample(2).count()
   ==>3
   ```
   
   The vertex example:
   ```
   schema.propertyKey("name").asText().ifNotExist().create();
   schema.propertyKey("price").asDouble().ifNotExist().create();
   schema.vertexLabel("product").properties("name", "price").nullableKeys("name", "price").create();
   schema.indexLabel("productbyname").onV("product").by("name").shard().ifNotExist().create();
   schema.indexLabel("productbyprice").onV("product").by("price").shard().ifNotExist().create();
   
   Vertex product1 = new Vertex("product").property("name", "product1").property("price", 3.254615);
   Vertex product2 = new Vertex("product").property("name", "product2").property("price", 4.5688);
   Vertex product3 = new Vertex("product").property("name", "product3");
   ```
   
   ### Vertex/Edge example (问题点 / 边数据举例)
   
   _No response_
   
   ### Schema [VertexLabel, EdgeLabel, IndexLabel] (元数据结构)
   
   _No response_
