模糊搜索匹配有问题？
一：设计想法：
1.搜索词分词(根据品牌名称匹配)
搜索词包含品牌词，品牌词包含搜索词，互相只要一项包含
(分词之后做同义词可能会匹配出其他品牌)
2.搜索词(不分词)
搜索词包含品牌词
(增加一个字段品牌词匹配字段,这个字段专门做匹配，比如字段值：小米,xiaomi,XIAOMI)

3.根据搜索词（不分词）包含问题？
搜索小米：搜索不到xiaomi.(业务组必须提供一个字段，来匹配搜索关键词)

二：根据搜索词(分词)后在包含
搜索小米(最大分词)：能搜索到xiaomi，由于是最大分词匹配。所以会匹配到，小，米。小米

总结:
如果用搜索词分词后匹配，词典里面必须配置品牌名称。而且，必须用ik_smart。但是匹配到同义词之后，还是会出现匹配到a这种情况

最终方案：
根据搜索词ik_smart分词（词典里面必须包含品牌词），然后根据品牌名称是否包含搜索词项。包含则匹配品牌
