------解决方案--------------------
从title,body字段中搜索 "Tutorial ",并按相关度从高到低排序
SELECT id, MATCH (title,body) AGAINST ( 'Tutorial ' IN NATURAL LANGUAGE MODE) AS score FROM articles ORDER BY score DESC;
------解决方案--------------------
一切皆有可能！
------解决方案--------------------
相关度排序是根据词元匹配，相关匹配算法可以从不同字元来匹配
看看开源的算法，比如海量开源
------解决方案--------------------
和数据库没有太大的关系。
任何数据都可以实现你说的功能。
你可以去网上下载个免费的PHP开源程序即可了解。
现在已经很多程序员开始用分词技术来实现相关信息的调用，因为它更准确，能为网站带来更多的PV（页面浏览量）
