Almost all Search Engines serve different countries’ Regional Search Engines ‘. Search Engines do list content from other countries but most of the content that is listed is either US or UK dominated content.
Regional Search Engines overview
With this in mind, most popular Search Engines have started deploying regional editions that serve only a specific country. For instance, Google has an Indian, South Africa and other countries edition (e.g http://www.google.co.in, http://www.google.co.za, http://www.google.co.uk, etc …) that caters to the Indian audience.
