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

[Alexander Barkov]

This is not a correct way to modify the character set file.
If you change the type of the dash character, you can break
MySQL parser - it will start to fail to parse certain types
of SQL queries.

The recommended way do make dash a word part for fulltext index
is to write your own fulltext parser using plugin interface
which was introduced in 5.1.

See the section "Full-Text Parser Plugins" of MySQL-5.1 manual:

http://dev.mysql.com/doc/refman/5.1/en/plugin-full-text-plugins.html

You can discuss how to write your own fulltext parsers at the
fulltext forum: http://forums.mysql.com/list.php?107
