New Rule of Google search

Many people often search often by searching Google Alerts for different country names (Google.com.uk or Google.com for Japan). This search facility is not available in different domains since today.

Google said in a blog post, country-based search results were changed. As a result, Google can not search any other country from now on. Instead of Google's new search, Google will show search results based on the user's location in search. That means that if you sit in Bangladesh or Google.com for Japan or Google.com for Japan, Google will send you a consistent search result for Bangladesh.

Google says that local search results do not show results as search by changing domain. It is not possible to find good results in your domain by searching other countries in the domain. That's why this step was taken.
