I am curious about it. These more than 10 years, I used many PHP based forums, all of which support global searching in Chinese, by default.
But in Flarum, Chinese searching is not supported by default. Additional searching drivers must be installed to achieve Chinese searching. I didn't test, but I guess Japanese, Korean and even most other non-latin languages, neither.
Searching is a basic need for most all users. But installing and configuring those drivers is not easy.
I know there must be a reason for Flarum not supporting Chinese searching by default. The detail is?
UPDATE: Thanks to GreXXL I tested on this site, input more than 3 (thus, at least 4) Chinese characters, the searching function will work, too. The remaining point is, most time, searching in Chinese will start in only 2 characters, because 2 Chinese characters could mean really a lot of information, like 90% city names and maybe 40% of people names, and so on.
Hope this could be heard and optimized in the future.
