配置文件data-config.xml定义了数据库的基本配置，以及导出数据的映射规则，即导出数据库表中对应哪些字段的值，以及对特定字段的值做如何处理

</dataConfig>

Solr的DIH暴露了请求中传递的变量 ${dataimporter.request.offset}，也就是在请求的requestHandler中可以附带附加属性条件，例如，下面请求URL中的offset=5000000参数：

http://172.0.8.212:8080/seaarch-server/core0/dataimport?command=full-import&offset=5000000

另外，还有一个参数是很重要的，它决定着是否清除已经存在的索引数据，默认为clean=true，如果不想删除以前的索引数据，一定要在请求的URL中指定该属性为false，请求URL如下：

http://172.0.8.212:8080/seaarch-server/core0/dataimport?command=full-import&offset=5000000&clean=false

另外，索引完成后一半需要执行commit操作，将内存中索引数据持久化到文件系统，防止改变丢失，所以需要在请求的URL中增加commit=true，例如：

http://172.0.8.212:8080/seaarch-server/core0/dataimport?command=full-import&offset=5000000&clean=false&commit=true
