原始表数据

搜索结果

排序失效

 (select * from keywords where name like '%中国奶粉%' order by replace(name,'中国奶粉','')) UNION (select * from 

(select * from keywords where name not like '%中国奶粉%') b where b.name like '%中国%' or b.name like '%奶粉%' ORDER BY b.num desc)

语句参考

关键词匹配：

select *,(case when name like '%中国奶粉%' then (select max(num)+1 from keywords limit 1) else num end) as new_num from keywords where name like '%中国奶粉%' or name like '%奶粉%' or name like '%中国%' order by new_num desc

商品匹配：

 

select * from sto_goods where goods_name like '%日本原装花王%' or goods_name like '%日本原装%' ORDER BY REPLACE(goods_name,'日本原装花王','');

或者根据关键词查询语句修改也可以。
