Solr 增量导入处理程序工作不正常

我遵循上面提到的步骤@:

http://wiki.apache.org/solr/DataImportHandler

我还尝试了stackoverflow的其他解决方案，但仍然不起作用

问题是： 每次运行Delta导入处理程序时，我仍然配置了它；它对数据库中的所有记录进行索引。 我有30条数据库记录。每次我运行delta import时，它都会索引所有30条记录。我只希望那些被更改/删除的应该被索引

对于此问题的任何快速帮助/指示/解决方案，我们将不胜感激

更改data-config.xml中的以下值已解决此问题

${dih.last\u index\u time}改为${dataimporter.last\u index\u time}

${dih.delta.id}改为${dataimporter.delta.id}

---

在调用delta import pass clean parameter=“false”时，我正在使用SOLR 4.0

，这将对您有所帮助

---

例如：域名：8983/solr/dataimport？command=delta-import&clean=false'

我正在使用这个：？command=delta-import&clean=false&commit=true仍然不适用于我
