结合一些分词组件,如盘古,对于用户查询关键字红按钮很容易分出 ‘红’ ‘按钮’二个单词
我们假设产品名称列里面是红色,规格里面是按钮
/*
普通sql实现全文搜索
declare @key1 nvarchar(50)
declare @key2 nvarchar(50)
declare @key3 nvarchar(50)
set @key1 = '%红%'
set @key2 = '%按钮%'
SELECT *
FROM [SYS_CHANPIN]
where 1=1
and [CPBM] = any(select [CPBM] from [SYS_CHANPIN] where cpmc like @key1 or cpgg like @key1 )
and [CPBM] = any(select [CPBM] from [SYS_CHANPIN] where cpmc like @key2 or cpgg like @key2 )
...................
and [CPBM] = any(select [CPBM] from [SYS_CHANPIN] where cpmc like @keyN or cpgg like @keyN )
*/
如果是linq就更简单了
string[] arraykeys = new string[]{"红", "按钮"}
from p in db.SYS_CHANPIN where arraykeys.all(key=>new string[]{p.CPMC,P.CPGG}.Any(column =>column.Contains(key))) select p
简单的来说,原理就是对于分组出来的每个单词,都必须在所查询列中满足至少一条,当所有的分词都满足条件时,既为这个数据为我们查询所需要的。
