我正在尝试在Sphinx中实现过滤器，以便可以从同一个联接表中的两个MVA属性（我需要的是双重条件，但由于MVA只有2个字段..）中过滤出结果，但是无论我做什么，由于multi属性的第一个字段始终存在匹配项，因此我似乎不断获得相同的结果？
也许还有另一种解决方案，但是我似乎无法找出如何获得期望的结果，我不得不简化4个表格：PRODUCT，CATEGORY，PRICE和POSITION。
下面的数据结构示例：
PRODUCT
+------+-------------+-----------------+---------------+
| ID | CATEGORY_ID | MANUFACTURER_ID | TITLE |
+------+-------------+-----------------+---------------+
| 1000 | 1000 | 1000 | Apple iPhone |
| 1001 | 1000 | 1000 | Apple iPad |
| 1002 | 1000 | 1000 | Apple iPod |
| 1003 | 1001 | 1001 | Do not show |
+------+-------------+-----------------+---------------+
CATEGORY
+------+-------+
| ID | TITLE |
+------+-------+
| 1000 | Apple |
| 1001 | Other |
+------+-------+
PRICE
+------+--------+---------+
| ID | USERID | PRICE |
+------+--------+---------+
| 1000 | 1000 | 359.00 |

| 1002 | 1002 | 1078.00 |
| 1003 | 1003 | 1160.45 |
| 1004 | 1004 | 1180.00 |
| 1005 | 1000 | 1190.00 |
| 1006 | 1000 | 228.76 |
+------+--------+---------+
POSITION
+------+------------+--------+------+
| ID | PRODUCT_ID | USERID | RANK |

Sphinx设置：

sql_user = ...
sql_pass = ...
sql_db = ...
sql_query_pre = SET NAMES utf8
sql_query = SELECT P.ID AS ID, C.ID AS SEARCH_CAT_ID, P.CATEGORY_ID, P.MANUFACTURER_ID, P.TITLE AS TITLE_SORT FROM CATEGORY C, PRODUCT P WHERE P.CATEGORY_ID=C.ID
sql_attr_uint = CATEGORY_ID
sql_attr_uint = MANUFACTURER_ID
sql_attr_string = TITLE_SORT
sql_attr_multi = uint POS_RANK from query; SELECT PRODUCT_ID, RANK FROM POSITION
sql_attr_multi = uint POS_USERID from query; SELECT PRODUCT_ID, USERID FROM POSITION
}
index product
{
source = product
path = ...
docinfo = extern
min_word_len = 1
}

SphinxQL查询过滤器USERID：
SELECT ID FROM product WHERE MATCH('1000') AND POS_USERID IN (1000) ORDER BY WEIGHT() DESC LIMIT 0,20 FACET POS_RANK LIMIT 5;
USERID的结果（这次第一次设置确定，第二次返回所有内容）：
+------+
| id |
+------+
| 1000 |
| 1001 |
| 1002 |
+------+
+----------+----------+
| pos_rank | count(*) |
+----------+----------+
| 5 | 1 |
| 4 | 1 |
| 3 | 1 |
| 2 | 1 |
| 1 | 3 |
+----------+----------+
我所期望的：
SphinxQL查询过滤器USERID 1000和RANK 5：
SELECT ID FROM product WHERE MATCH('1000') AND POS_USERID IN (1000) AND POS_RANK IN (5) ORDER BY WEIGHT() DESC LIMIT 0,20 FACET POS_RANK LIMIT 5;
USERID和RANK的结果（这次第一组似乎确定，第二组返回所有内容）：
+------+
| id |
+------+
| 1001 |
+------+

| pos_rank | count(*) |
+----------+----------+
| 5 | 1 |

SELECT ID FROM product WHERE MATCH('1000') AND POS_USERID IN (1000) AND POS_RANK IN (4) ORDER BY WEIGHT() DESC LIMIT 0,20 FACET POS_RANK LIMIT 5;
USERID和RANK的结果（第一个stil返回产品，第二个返回所有结果）：
