我正在尝试以下查询:
gV(835776).out('Follow').in('WallPost').order().by('PostedTimeLong', decr).range(0,2)
我得到以下回应:

由于同一个帖子发布在两个不同的 ID 上,因此它会出现两次响应。我想根据顶点 id 按响应分组(两者都有相同的顶点 id。或者我只想从它们中取出一个对象,因为两者都是相同的。
我尝试了以下查询,但对我没有任何帮助:
gV(835776).out('Follow').in('WallPost').groupBy{it.id}.order().by('PostedTimeLong', decr).range(0,3)
gV(835776).out('Follow').in('WallPost').group().by(id).order().by('PostedTimeLong', decr).range(0,3)
如何根据顶点 ID 按结果分组。
