I hope anyone can share his experience or thoughts about the use of
datastore cursors in URLs that are to be crawled by search engines.

Scenario: I have a page with news items in reverse chronological order
(most recent on top). The data for the page is obtained by a query and
the current cursor is also returned and embedded in the "Next Page"
link. So when the user clicks "Next Page", the cursor is passed back
to the server and the query returns the next X results and so on.

Now my question is whether this design where the cursors are embedded
in the "page URL" plays nicely with Search Engines that would remember
the link and the content in the page. If a user hits a URL from a
search engine that contains the cursor as a parameter, possibly months
later - would the query&cursor still return the same content?
(assuming entries are not removed from the datastore, but newer
stories are constantly added to the "top" of query).

Anyone sees any issues with this approach?

Thanks,
Michael
