Johann,
These queries have different second parameters in their Key.from_path. Is
this just a text error?
Domain.all(keys_only=True).order('__key__').filter('__key__ >=',
db.Key.from_path('domains_domain', 'menewokzxwsqipne')).fetch(100)
Domain.all(keys_only=True).order('-__key__').filter('__key__ <=',
db.Key.from_path('domains_domain', 'mengame')).fetch(100)
