PEAK XOOPS - FULLTEXT KEY in XOOPS

There are some modules using "FULLTEXT KEY" in mysql.sql.
But I can find no queries with "MATCH()".
This makes useless indexes, and can harm its performance.

Moreover, MySQL does not support "splitting words" for multibyte language.

I will check the performance of ...

- "splitting words" by kakasi, chasen, or mecab
- implode the words by a space into a string
- stores the string into a column for searching
- query with MATCH()
