Is there a way to search the datasets of all Federal government organization type?
Thanks to Philip Ashlock for providing the following answer:
These are both known, but unfortunately unresolved issues. You can track their status on github at https://github.com/GSA/data.gov/issues/294 and https://github.com/GSA/data.gov/issues/492. You can still filter by type using the web UI though, eg https://catalog.data.gov/dataset?organization_type=Federal+Government
