I use the url to search channels in a specific country like this https://www.googleapis.com/youtube/v3/search?part=snippet&maxResults=8&order=viewCount&q=news&type=channel®ionCode=US&key=API-Key.
But when i changed the regionCode parameter to IT(italy) or any other one,the search result is always identical.So the search result is not changed with the regionCode.
How can I search the channel by country using the YouTube API 3.0,thanks.
