Subject: Full text search not matching 2 letter word

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)) ;

field trial.              | PHOTO   | DISPLAY         | STORAGE

Any ideas why this is not working?

Thanks
