两个月过去了，我仍然有这个问题，我不知道如何解决。你找到解决办法了吗？没有。我认为这是预期的行为，因此必须获取地理查询中涉及的文档。我可能会创建一个只包含点和文档id的专用集合，这样获取的文档会更轻。然后我可能会在更大的区域查询上使用另一个索引。您现在找到解决方案了吗？正如前面的评论中所述：我认为$geointen不是一个线性操作，因此不能用于“infinete”集合。当我搜索住宿时，我总是有一个搜索区域，比如一个城市或一个州，让我们把它命名为“项目”，它有一个id。所以我预先计算了项目区域中的住宿，并将项目id添加到住宿中的和数组中。将索引添加到数组中并在其上进行查询是非常有效的。如果没有该项目，我将从$centerSphere中包含的较小项目中搜索
