Is myisam/ft_static.c a file? If so, where is it located? I can't find it on my machine. I can't even find any myisam directory or file.

Will the absence of ft_static.c cause a large performance degradation if I set ft_min_word_len to 3 instead of the default 4?

After resetting ft_min_word_len, is "REPAIR TABLE tbl_name QUICK" the best way to have the changes take effect?

Do I have to restart mySQL before running REPAIR TABLE tbl_name QUICK?

Thanks.
