分面搜索具有多个值的字段
faceted search for field with multiple value
我有一个 table where 字段有多个逗号值:
+------+---------------+
| id | education_ids |
+------+---------------+
| 3 | 7,5 |
| 4 | 7,3 |
| 5 | 1,5 |
| 8 | 3 |
| 9 | 5,7 |
| 11 | 9 |
...
+------+---------------+
当我尝试使用分面搜索时:
select id,education_ids from jobResume facet education_ids;
我收到这样的回复:
+---------------+----------+
| education_ids | count(*) |
+---------------+----------+
| 7,5 | 3558 |
| 7,3 | 3655 |
| 1,5 | 3686 |
| 3 | 31909 |
| 5,7 | 3490 |
| 9 | 31743 |
| 9,6 | 3535 |
| 8,2 | 3547 |
| 6,2,7 | 291 |
| 7,8,1 | 291 |
| 1,2 | 3637 |
| 7 | 31986 |
| 5,9,7 | 408 |
| 1,1,5 | 365 |
| 5 | 31768 |
| 3,8,3,7 | 32 |
| 3,7,6 | 431 |
| 2 | 31617 |
| 5,5 | 3614 |
| 9,9,2,2 | 6 |
+---------------+----------+
但这不是我想看到的。我想每个值都有自己的计数,例如这里:
+---------------+----------+
| education_ids | count(*) |
+---------------+----------+
| 10 | 961 |
| 11 | 1653 |
| 12 | 1998 |
| 13 | 2090 |
| 14 | 1058 |
| 15 | 347 |
...
+---------------+----------+
我用sphinx能得到这样的结果吗?
确保使用 MVA,而不是字符串属性:
index rt
{
type = rt
rt_field = f
rt_attr_multi = education_ids
path = rt
}
snikolaev@dev:$ mysql -P9306 -h0
