How many pages do your users really want to see? Even Google search
sets a limit - I think 1000 results. Although the number of results
can exceed 1000 the offset is still limited so you would need to
filter out results to continue past 1K. That would be slow.
If you really need to return more than 1000 results and access them in
forward and backward directions you could sort them by __key__ or some
other unique combination and use that as you own "cursor". You could
define both ascending and descending indexes on your chosen
property(s) to let you iterate in both directions.

But isn't it getting slower and slower on higher pages, since it
fetches ALL data (according to docs) and discards the offset value?
So Range(0,10) is faster than Range(10000,10) ?
Anyone did some performance tests?

Probably you should set an offset and limit instead for your paging.
I believe cursors are really intended for processing a lot of data
off-
line. Remember there is no longer a 1000 result limit on fetches.

Hi,
Is there a way to get a cursor to page back to a previous page?
If not, whats the point of paging forward only? I'm not building an
ajax page.
