China’s major player in the search engine market is known as Baidu. Of course most of the instructions are written in Chinese so it is not easy for a western visitor to use advanced search commands without the help of a quick reference cheat sheet. For starters, Baidu has a web page off of its main portal to do advanced searches. However, the problem for westerners is that it is all in Chinese with no button for switching to another language like English. To reach the advanced search page, go to the URL:

The best way to use the advanced search features is to translate the fields. This can be accomplished by using a web translation portal such as Yahoo’s Babel Fish. Just enter the link to the advanced page in the web page translation field. For the source and target languages, choose “simple Chinese to English.” While the translation is not exactly correct, it is close enough for an English-speaking visitor to make use of. The following table lists the fields on the advanced search page and their functionality. Some of these advanced search functions can also be accessed from the main Baidu search page and the second column in the table lists an example of how to invoke it. Note that the field label is the translation returned by Babel Fish and does not reflect correct English grammar in each case.
