mysql 全文检索

手册上的内容：
MySQL   has   support   for   full-text   indexing   and   searching:  

A   full-text   index   in   MySQL   is   an   index   of   type   FULLTEXT.  

Full-text   indexes   can   be   used   only   with   MyISAM   tables,   and   can   be   created   only   for   CHAR,   VARCHAR,   or   TEXT   columns.  

A   FULLTEXT   index   definition   can   be   given   in   the   CREATE   TABLE   statement   when   a   table   is   created,   or   added   later   using   ALTER   TABLE   or   CREATE   INDEX.
