使用 int 主键的 Sphinx 搜索

Question

我正在尝试将 int 主键添加为 sql_field_string，当我旋转索引时，我收到消息：警告：未找到属性 'purchase_id' - 忽略

我的配置：

sp_purchases_source : sp_source_config
{

        sql_query = \
                SELECT sp_purchase.id AS purchase_id, sp_purchase.status, sp_purchase.name, sp_purchase.description_small, sp_purchase.description_full, sp_purchase.news,\
                UNIX_TIMESTAMP(sp_purchase.date_current) AS date_current, UNIX_TIMESTAMP(sp_purchase.stop_date) AS stop_date, sp_purchase.image, sp_purchase.access, \
                sp_purchase.is_vip, sp_purchase.is_foreign, sp_purchase.owner_username, sp_purchase.owner_id, sp_purchase.count_users, sp_purchase.count_comments \
                FROM sp_purchase \
                WHERE sp_purchase.is_hidden = 0 AND sp_purchase.status IN (2,4,17)

        sql_ranged_throttle = 0
        sql_field_string    = purchase_id
        sql_field_string    = name
        sql_field_string    = description_small
        sql_field_string    = description_full
        sql_field_string    = owner_username
        sql_field_string    = news
        sql_attr_timestamp  = date_current
        sql_attr_timestamp  = stop_date
        sql_attr_string     = image
        sql_attr_uint       = access
        sql_attr_uint       = owner_id
        sql_attr_uint       = status
        sql_attr_bool       = is_vip
        sql_attr_bool       = is_foreign
        sql_attr_uint       = count_users
        sql_attr_uint       = count_comments
}

如何在索引中添加 id 字段？

Answer 1

好吧，document-id 已经了一个虚拟属性。它就像一个真正的属性一样工作。

也可以 filter/sort/group 按 id。

sphinxql> SELECT id,name FROM sp_purchases WHERE id BETWEEN 10 and 20;

...要使它成为一个字段，必须更棘手一些，例如将其复制两次。

    sql_query = \
            SELECT sp_purchase.id, sp_purchase.id AS purchase_id, sp_purchase.status, ...

第一列是总是 document-id，所以将用于虚拟属性。

因此 purchase_id 成为 'standard' 字段。
