Profile Search Requires Wildcard
Using Jamroom
The problem here is that "ChinaNews" is a very different word than "China". "China News" (with space) will be found or course, but without the space the full text index is not going to see "chinanews" as being the same as "china". Make sure in ACP -> Listing -> Search -> Global Config you have enabled the "Include Partial Matches" option.
In reality I think you'll find this to be a non issue when searching your site.
Let me know if that helps.
