云开发怎么从集合的后面获取数据啊，或者怎么将新数据插到集合的最前面？How does cloud development get data from the back of the collection, or how to insert new data at the top of the collection?

To do a page turning function, the first page is required to be the latest information, but I found that the cloud development database can only insert the new data to the end of the collection, and then get the data from the front of the collection. Is there any way to get data from the back of the set, or insert new data to the front of the set? (I tried the method of orderby. In fact, it is equivalent to sorting the acquired data, rather than sorting the data in the collection.
