OS X Yosemite spotlight search wikipedia and web content missing

One of the new features in spotlight was supposed to be information from wikipedia, web when anything was searched. However, I don't seem to be getting this information when I search in spotlight. Is this feature only available in certain countries? (Im in India, and all the reviews I've read about Yosemite are US or Europe based websites).

It's a list of countries that have Spotlight Suggestions enabled in iOS 8. If this is true, this is a pretty bad move from Apple.

UPDATE: Apple confirms that

Spotlight Suggestions may not be available in all regions.

on the Spotlight support page.

Appart from @shrx correct answer there is a second issue with Yosemite's new Spotlight feature:

On my system I was able to enable Wikipedia and Web content by aligning my system's region and language settings.
