RADB lookup help

[John Fraizer <nanog () Overkill EnterZone Net>]

I'm trying to do the equiv of "whois -h rr.arin.net -i origin as13944" at
whois.radb.net but am not having any luck.  Is there a way to form this
query at whois.radb.net?

I'm simply looking for all objects registered with an origin of as13944.

Thanks,
