I backup and reinstall nodebb v0.6 instead of 0.7 and the problem is solverd.
Thanks for your time
Problem with searching in admin panel.
Search in Admin Panel needs to input at least 3 characters.
But in Chinese, lot's of words only have 2 characters.
For example, "邮件"(Email) "用户"(User) "板块"(Categories).
So annoying when you want to find something.
I want to change the default "Post Sorting", and I can't just search "排序" in Chinese.
I need to change my language to English, refresh Admin page, then search "sort".
Hey, good catch. I've opened an issue on Github: https://github.com/NodeBB/NodeBB/issues/5563
