If you are a serious Googler, then you will know the fact that indexed data for the same search terms will vary depending on the Google server that’s queried.
If you are searching for a particular thing in India, the query is automatically directed to Google.co.in servers and the data indexed in Google.co.in will be different from the data that’ll be indexed in Google.com . The results returned from Google.co.in will be localized and hence the difference.
All your queries, by default will go to your local Search center and if in case you want to query to base Search Center then use this link.
