Hello, Professor Purandar,
Thank you for your interest in Microsoft Academic Search! And thank you for alerting us that IIT Kharagpur and IIT Guwahati are not included as academic organizations.
We will send a request to our technical team to add IIT Kharagpur and IIT Guwahati as organizations on the website. This can take some time to process. Thank you for your patience.
Please let us know if we can be of any other assistance. We hope you continue to explore and enjoy our site.
Best regards,
Thomas, Academic Search Editor
