modify a character set file: add & and - as word characters

[Sean Fang]

Hi,

I'm using fulltext search and need to make & and - word characters in the fulltext indexes.

I read the foolowing message from online reference manual at dev.mysql.com:

================================================
Modify a character set file: This requires no recompilation. The true_word_char() macro uses a “character type” table to distinguish letters and numbers from other characters. . You can edit the <ctype><map> contents in one of the character set XML files to specify that '-' is a “letter.” Then use the given character set for your FULLTEXT indexes.
================================================

But it looks quite remote to me since I'm very experienced with fulltext search yet.

I was able to find the character set files in mysql/characters/ folder. BUT, i don't know where to start adding them to <ctype><map> contents and later how to rebuild the fulltext indexes using the character set file?


Can anyone please help? I'm not sure what dev.mysql.com was thinking about by puting such a not step-by-step detail-level manual online to help beginners like me?

Thanks,
