在solrImportScheduler中，为什么我们需要为增量导入定义reBuildIndexBeginTime？

Question

在wiki页面http://code.google.com/p/solr-dataimport-scheduler/上

params=/dataimport?command=delta-import&clean=false&commit=true
interval=1

这条线的目的是什么？

reBuildIndexBeginTime=03:10:00

如果我注释掉reBuildIndexBeginTime=03:10:00 ，那么索引就不会为delta 运行。什么是reBuildIndexBeginTime=03:10:00，为什么我们将它用于增量导入？

dataimport.properties文件在我的solr-多核安装中

好吧，正如我所承诺的，这里是。干净的数据导入处理程序计划程序编译源代码。
