数据结构：

houses (collection)
  name (string)
  users (map)
    90c234jc23 (map)
      percentage: 100% (string/number)

规则：

allow read: request.auth.uid in resource.data.users;

问题是当我尝试查询用户拥有的房屋时：

FirebaseFirestore.getInstance().collection(House.COLLECTION)
//                .whereArrayContains(House.USERS_FIELD, currentUser.getUid()) // does not work
                .whereEqualTo("users." + currentUser.getUid(), currentUser.getUid()) // does not work either
                .get()

不返回任何结果。
