Problem: ======= By keeping innodb_ft_min_token_size = 0, InnoDB FTS does tokenization on empty string and tries to add the nullptr as token word. This leads to crash when we try to convert the token into lower case characters. Solution: ========= The minimum value of innodb_ft_min_token_size should be 1. It should be consistent with MYISAM and ARIA engine.
