    大数据量为了避免全表扫描，不使用like，那应该怎么去查询呢？

    必须用全文检索引擎么？

    有没有更简单点的解决方案？

    @binux 谢谢，不过貌似mysql自带的全文检索对中文支持不太好的样子？

    @cleverUtd 谢谢，了解一下这个看可不可行。

    @582033 1楼说的key-value就是传说的nosql.. 如mangoDB,redis啥的

    @582033 不是吧，列存储你可以看看其中的一种 infiniDB，它是基于mysql的，对于sql中的like 响应性能不错；另外如果要用到全文检索的话推荐一款叫sphinx，也是基于mysql的。
