As noted in a previous post, Xu Zhiyong (许志永), a Beijing lawyer described by the state-sponsored China Daily as someone who "has been providing legal help to the country's disadvantaged groups" was detained on July 16, 2013. Sina and Tencent began censoring searches for his name on their respective Weibos shortly thereafter.
These screenshots show that on July 19, 2013 the top Baidu search result for "Xu Zhiyong" was Baidu's own Baidu Encyclopedia (百科 Baike) entry for Xu. The same search on July 20 shows that the top result for Xu is now Xu's Wikipedia entry and Baidu's Encyclopedia entry is not on the first page of results.
The reason is that the Baidu Encyclopedia entry, originally available here - http://baike.baidu.com/view/1669218.htm - appears to be because it has been deleted. The screenshot below shows what users clicking on that URL saw on July 20 - a notice saying "Apologies, we are unable to display the article you wanted to access!" (对不起，您所要查看的词条无法显示！)

As of July 20, 2013, Soso's Encyclopedia entry for Xu remained available here - http://baike.soso.com/v47143757.htm.
