Question

所以我的sphinx.conf文件包含类似的东西。基本上我使用delta索引来快速制作。

source main
{
    #...

    sql_query_pre   = SET NAMES utf8
    sql_query_pre   = REPLACE INTO sph_counter SELECT 1, MAX(id) FROM photo

    sql_query       = \
        SELECT p.id AS id, p.search AS search, COUNT(li.id) AS total_likes \
            FROM `photo` p \
            LEFT JOIN `like` li \
            ON p.id = li.photo_id \
            WHERE p.id <= ( SELECT max_doc_id FROM sph_counter WHERE counter_id=1 ) \
            GROUP BY \
            p.id

    #...

    sql_query_info      = SELECT * FROM photo WHERE id=$id
}


source delta : main
{
    sql_query_pre   = SET NAMES utf8
    sql_query       = \
        SELECT p.id AS id, p.search AS search, COUNT(li.id) AS total_likes \
            FROM `photo` p \
            LEFT JOIN `like` li \
            ON p.id = li.photo_id \
            WHERE p.id > ( SELECT max_doc_id FROM sph_counter WHERE counter_id=1 ) \
            GROUP BY \
            p.id
}

在我检索数据的时候，我也希望有一些排序方法。

$s->SetSortMode(SPH_SORT_EXTENDED, '@relevance DESC, total_likes DESC, @id DESC');
$result = $s->Query($data['query'], "delta main");

当我只有main索引时，排序工作正常。但是现在当我使用两个索引进行搜索时，delta索引的结果会附加在前面。我真正想要的是两个索引的结果被提取然后根据偏好排序，即在我的情况下@relevance DESC, total_likes DESC, @id DESC。 total_likes应优先于id

感谢@barryhunter solution。解决方案是在delta索引中第二个sql_query_pre必须被覆盖。

sql_query_pre = SET NAMES utf8
    sql_query_pre =
    sql_query = \

sphinx中的SetSortMode不使用delta索引
