Google News XML API: use country/language parameters

问题

I would like to subscribe to an RSS/XML feed from Google News that captures the following query:

Articles mentioning "studie" (German for "study"), written in German, emanating from any country.

I'm using https://news.google.com/rss/search, but for this example, it's easier to see the UI output at https://news.google.com/search, so I'll use the latter URL base in this example.

Now, in the XML API reference, Google mentions four different parameters that influence either language or country:

hl (host language): the language that the end user is assumed to be typing in. I.e., an English-language speaker types "study," and Google assumes that term is in English and then machine-translates the results back to English. For me, navigating to will redirect a URL with hl=en-US (full URL is https://news.google.com/?hl=en-US&gl=US&ceid=US:en).
gl: boosts search results whose country of origin matches the parameter value. The default in my web browser is gl=US.
lr (language restrict): restricts search results to documents written in a particular language
cr (country restrict): restricts search results to documents originating in a particular country

Based on all of the above, that would imply a URL of*:

https://news.google.com/search?q=study&hl=en-US&lr=lang_de

That attempt, however, fails miserably; it shows English-language results from the U.S., and it 302 redirects to:

https://news.google.com/search?q=study&lr=lang_de&hl=en-US&gl=US&ceid=US:en

So, to that end:

How can I properly structure URL parameters to capture 'Articles mentioning "studie" (German for "study"), written in German, from any country.'?
What the heck is ceid and why is it documented absolutely nowhere by Google?

* I.e.:

>>> import urllib.parse
>>> urllib.parse.parse_qs('q=study&hl=en-US&lr=lang_de')                                                                                                     
{'q': ['study'], 'hl': ['en-US'], 'lr': ['lang_de']}
