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".

Word: Moderation note saved
"修改未保存" is incorrect, means "The changes are not saved".
The correct translation is "版主备注已保存" or "版主留言已保存".

Also, I think to translate all "note" to "备注" instead of "留言" is better.
"留言" is more like the note is visible to the user.

@PitaJ WOW thanks. Didn't think about that.I'm new with node.js.

Solved in a dirty way.
I changed ./src/socket.io/index.js about line 60,added pingInterval and pingTimeout.
I was expecting to change this by a plugin, not edit Nodebb's code directly.(seems not possible)

How can I change socket.io's "heartbeat interval" and "heartbeat timeout"?
Or how can I manually send a heartbeat pack?
I can make a plugin, but no idea how to do it right now.
