From the 5.0.18 manual pages:

12.7.5. Fine-Tuning MySQL Full-Text Search

Most full-text variables described in this section must be 
set at server startup time. A server restart is required to 
change them; they cannot be modified while the server is 

Some variable changes require that you rebuild the FULLTEXT 
indexes in your tables. Instructions for doing this are 
given at the end of this section. 

The minimum and maximum lengths of words to be indexed are 
defined by the ft_min_word_len and ft_max_word_len system 
variables. (See Section 5.2.2, Server System Variables.)

The default minimum value is four characters; the default 
maximum is version dependent. If you change either value, 
you must rebuild your FULLTEXT indexes.

For example, if you want three-character words to be 
searchable, you can set the ft_min_word_len variable by 
putting the following lines in an option file:


Then you must restart the server and rebuild your FULLTEXT 
indexes. Note particularly the remarks regarding myisamchk 
in the instructions following this list. 



In theory, theory and practice are the same;
in practice they are not.
