mysql命令按逗号分隔字段中的匹配项

Question

I have one blog table which contains different tags,

now i want to order blog by max tag match

and am storing tags comma separated in one field

now how to do that?

I tried find in set but still dident get work.

Please suggest me any better way to do so.

table like:

id | title | desc      | tags

1 | test1 | test1 desc | t1,t2,t3,t4

2 | test2 | test desc  | t1,t2

3 | test3 | test desc  | t1,t2,t3

4 | test4 | test desc  | t3,t4

5 | test5 | test desc  | t1,t2,t3,t4

here suppose i want closest blog post of "test1" post then answer should be 5,3,2,4

first match with tags and after that if same tag count then by id

您应该首先将标签分成不同的表。
