I want asking a question that when I enter some words can not search at "SEARCH→BASIC→CONTENT" function, but when I enter "9999" or "AAAA" can search it.
Does the function support "CHINESE"?

For chinesse characters is necessary change default lucene configuration parameters. I can confirm to you can work with chinese because we got some customers from this country. Take a look here http://wiki.openkm.com/index.php/Indexing_configuration

Which folder I can add "hibernate.search.analyzer=org.apache.lucene.analysis.cn.ChineseAnalyzer"?
At "Administration>Config" or "OpenKM\tomcat\OpenKM.cfg" ?

Yes, Take in mind there're two chinese variants traditional and simple. I think is not exactly the same analyzer, take a look with care about it.
