So far I haven't been able to figure out the search function's rules for Chinese characters. I admit I didn't check any online forums/documentation on Discourse for help with that problem, but I had a sneaking suspicion that searching for Chinese characters is not gonna be a priority for many folks out there (in fact it may not be anybody's priority in here, but I'm already registered here ).
To give some examples of my problem figuring out what the search function allows and doesn't allow:
The sequence of Chinese characters for Toufen Township (頭份鎮) is on this board, as this Google search shows:
But if I search for that sequence of characters (頭份鎮) using the board's search function, I get this result:
I get a different result, though, if I search for the TV series 風水世家 (Fengshui World Family?):
If I infer from the difference between the two results that the search function requires more than three characters, and then try the sequence of characters for Miaoli County, Toufen Township, (苗栗縣頭份鎮), which is shown in the first example to exist on the board; then I get this result:
So it appears that the reason that the search function will bring up 風水世家 but not 頭份鎮 is not necessarily related to the difference in the number of characters in the two expressions.
Out of an abundance of caution, I admit that there is a distinct possibility that I've made some error or another of a glaringly obvious sort. But if I've made such an error, I'm hoping someone will point out what it is, because I sometimes like to plug Chinese characters into the search function.
