Search every dataset listed on Australia's government open-data portals

Words in q are matched against title, description and publisher, with plurals and other endings matched to their stem. Records that can take a vote come first. With ids, returns those records by id or vote key, and answers the id of a copy the catalogue dropped with the record that replaced it, naming each such pair in moved; with url, returns the record a portal URL names, or null. Each row's state is votable, chosen (planned in the register; its vote key is the register slug), served (it has a page here) or closed (no open licence or no file to read, with the reason).
