We’re sorry… … but your computer or network may be sending automated queries. To protect our users, we can’t process your request right now.
I already told about Google refusing to process your search requests and requiring to enter a captcha. Now they don’t even offer to enter captcha, just show “We are sorry” page. However the error seems to appear only if you use the browser search bar. If you open the actual Google page and enter the same search query there, it works no problem.
