Please see the documentation:

q=
Query string to search for.

Alternatively can be entered as:
street=
city=
county=
state=
country=
postalcode=
(experimental) Alternative query string format for structured requests. Structured requests are faster and require less server resources. DO NOT COMBINE WITH q= PARAMETER.

If you want to use country with q= the only option is countrycode=

Actually, you want to read the query again. I'm not using 'q' option at all here.

FWIW, I had a chat with lonvia about this on IRC and she told me that its a bug so I filed it here.
