….starting today we’ll notify users in mainland China when they enter a keyword that may cause connection issues. By prompting people to revise their queries, we hope to reduce these disruptions and improve our user experience from mainland China. Of course, if users want to press ahead with their original queries they can carry on.
In order to figure out which keywords are causing problems, a team of engineers in the U.S. reviewed the 350,000 most popular search queries in China. In their research, they looked at multiple signals to identify the disruptive queries, and from there they identified specific terms at the root of the issue.
