I think I'm seeing the same problem. I have recently (in the last 3 days) added descending indexes on __key__ for two models, and they should return very similar entries because for each domains_domain model instance, there should be a dns_lookup instance. It works okay for __key__ ascending and for a separate string property called "backwards" both ascending and descending, but the new descending __key__ indexes return only partial results. It seems that maybe 40% of items are missing from the descending __key__ indexes.
I have a rather large dataset (2,203,599 items, 15.7 GB including metadata). The App ID is scoretool. You can see the problem if you visit http://scoretool.appspot.com/dns/cron/ and hit refresh until you get "Selector: before [random string]" and the text "Created [number] missing DNS lookups:" followed by "(not really)". My complete source code is available: http://github.com/jcrocholl/scoretool/blob/master/dns/views.py http://github.com/jcrocholl/scoretool/blob/master/prefixes/selectors.py Please let me know if I can do anything else to help diagnose this problem.
