derby.js如何在已排序的集合上使用$ skip和$ limit查询？

Question

Sorry if this is a dump question but I cannot figure it out.

As collections grow in size, it become convenient to render a portion of the data. For that we can something like

model.query('items', { $skip: 30, $limit: 30 })

but what if we want to do that on a filter or a sort? I have tried

model.query('items', { $skip: 30, $limit: 30 }, { creation_time: -1})

to mimic MongoDB .find() .

I haven't find a way to do a fetch/query on filters. Of course I don't want to slice after .get() since that would be problematic on large collections. I tried to use a ref() on filter with no success. Does someone know a recipe on how to handle those situations?

Thanks in advance.

PS: I hope .fetch() hold a cursor and wait for .get() to retrieve data.

model.query('items', { $skip: 30, $limit: 30, $orderby: {creation_time: -1}})
