For InnoDB, you need to change innodb_ft_min_token_size, as ft_min_word_len is for MyISAM only:

Im trying to run a full text query on a two letter keyword 'K7'. I have set ft_min_word_len=2 and restarted the server and if I view the system vars in Mysql Workbench it shows it is set correctly.

I have then dropped and re-created the index on the descrip column. It is an InnoDB table so I cannot do repair table.

Im running the following query which I expect to match the following record but it doesnt. Full text searches for other words match OK.

select * from asset where type ='DOCUMENTS' and (match(descrip) against ('K7' in boolean mode)) ;
