domain, language, and countries: ft_v2_api()

[lauren0707]

Hi - thank you so much for building this package. I'm having a bit of trouble filtering by domains, source_language, and/or source_countries with the ft_v2_api() command and was curious if you could provide any examples showing the correct syntax. The problem is that I'm writing the domain names, languages, and countries, but it is still providing the whole universe of the articles that contain my key words (not filtering by my additional parameters). The command does correctly search for terms, but does not encompass my additional restrictions.

Thank you so much!
