As I mentioned in my previous message, these operators are not native to the GAE datastore, but are implemented by doing multiple queries and aggregating the results. So it's not a simple matter to add support for these operators to OpenBD. However, if you're really interested in tackling this work I'll be happy to point you to the code.
