注意：

　　任何一项配置，如果在新的数据源块中指定了新值，继承的值都将被忽略，即使有多个定义（ multivalue）－－也就是说在一个块中如果某个类型的定义有多个，如果在新块中定义了该类型的一个新值，那么继承来的该类型的整个列表都将被忽略。所以discuz source中指定的 sql_query_pre = SET NAMES utf8对threads source不起作用。

启动：

searchd

查看是否启动：

# netstat -anp | grep searchd

tcp               0.0.0.0:            0.0.0.0:*      LISTEN      /searchd

tcp               0.0.0.0:            0.0.0.0:*      LISTEN      /searchd

建立索引：

indexer --all
