sphinx （coreseek）——3、区段查询 与 增量索引实例

首先本文测试数据100多万的域名的wwwtitle 信息  检索数据：

• 首先建立临时表格:

CREATE TABLE `sph_counter` ( 
`index_id` tinyint(1) NOT NULL, 
`max_id` int(11) NOT NULL, 
PRIMARY KEY (`index_id`) 
) ENGINE=MyISAM DEFAULT CHARSET=utf8

• csft.complex.conf 文件修改配置：

#增量数据索引 区段查询 合并为一个文件实现 测试 配置文件
#数据源
source src
{
        # data source type. mandatory, no default value
        # known types are mysql, pgsql, mssql, xmlpipe, xmlpipe2, odbc
        type                    = mysql

        #####################################################################
        ## SQL settings (for 'mysql' and 'pgsql' types)
        #####################################################################

        # some straightforward parameters for SQL source types
        sql_host                = localhost

        sql_pass                = 201671zhuang
        sql_db                  = whomx
        sql_port                = 3306  # optional, default is 3306
        sql_query_pre          = SET NAMES utf8
        sql_query_pre          = SET SESSION query_cache_type=OFF
        sql_query_pre          = REPLACE INTO sph_counter SELECT 1, MAX(id) FROM mx_domain_wwwinfo
        #分次查询数据，不要一次将全部数据取
        sql_query_range         = SELECT MIN(id), (SELECT max_id FROM sph_counter WHERE index_id = 1) FROM mx_domain_wwwinfo
        #每一次的 数据条数量
        sql_range_step          = 10000
        sql_query               = 
                SELECT * 
                FROM mx_domain_wwwinfo 
                WHERE id>=$start AND id<=$end
         sql_query_info          = SELECT * FROM mx_domain_wwwinfo WHERE id=$id
}
# 表示增量数据源
source moresrc : src
{
        sql_query_pre          = SET NAMES utf8
        sql_query_pre          = SET SESSION query_cache_type=OFF
        #增量索引实现
        sql_query_range        = SELECT (SELECT max_id FROM sph_counter WHERE index_id=1),MAX(id) from mx_domain_wwwinfo
        sql_range_step          = 10000
        sql_query              = 
                SELECT * 
                FROM mx_domain_wwwinfo 
                WHERE id>=$start AND id<=$end
        sql_query_post                  = 
                REPLACE INTO sph_counter SELECT 1,MAX(id) FROM mx_domain_wwwinfo
        #获取数据后，改写sph_counter增量索引计数表中的数据
}
