Google Scholar requires the following database definition in config.txt:
Title Google Scholar
In October 2007, Google started redirecting international domains from scholar.google.com to the localized version. It is not necessary to include all of the international variation, but rather just the one that is appropriate for your country. If other international sites notice a similar redirection to their own country's version, please please report this to email@example.com so this page can be further updated.
