   <!-- Answer -->
   HugeGraph Java 客户端的类型化 API（如 VertexAPI）目前不支持通过 P.contains(["xxx"]) 
这样的高级谓词进行属性过滤。类型化 API 只支持简单的属性等值过滤，无法表达更复杂的条件。
   
   如果你需要用 P.contains 进行集合属性过滤，可以通过 Gremlin 脚本 API 实现。Java 客户端提供了 GremlinRequest 
类，可以提交任意 Gremlin 查询。例如：
   
   ```java
   String gremlin = "g.V().has('yourLabel', 'yourProperty', within('xxx'))";
   ResultSet result = new GremlinRequest.Builder(gremlin, 
gremlinManager).execute();
   ```
   
   你可以将 Gremlin 查询字符串和参数通过 GremlinRequest 提交到 HugeGraph Server，支持所有 Gremlin 
的谓词和语法，包括 P.contains、within 等复杂条件。[GremlinRequest

   如果你希望类型化 API 也支持类似 P.contains 的过滤，欢迎提交 PR 扩展相关功能。如果需要进一步的代码示例或文档指引，也可以继续提问。
