多值字段的多面搜索

Question

我有一个表，其中用逗号表示多个值的字段：

+------+---------------+
| id   | education_ids |
+------+---------------+
|    3 | 7,5           |
|    4 | 7,3           |
|    5 | 1,5           |
|    8 | 3             |
|    9 | 5,7           |
|   11 | 9             |
...
+------+---------------+

当我尝试使用多面搜索时：

select id,education_ids from jobResume facet education_ids;

我正在收到此回复：

+---------------+----------+
| 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 |
+---------------+----------+

但是那不是我想要看到的。我想每个值都有自己的计数，例如在这里：

+---------------+----------+
| education_ids | count(*) |
+---------------+----------+
|            10 |      961 |
|            11 |     1653 |
|            12 |     1998 |
|            13 |     2090 |
|            14 |     1058 |
|            15 |      347 |
...
+---------------+----------+

我可以用狮身人面像得到这样的结果吗？

请确保您使用的是MVA，而不是字符串属性：

index rt
{
    type = rt
    rt_field = f
    rt_attr_multi = education_ids
    path = rt
}
