如何修复损坏的lucene索引？

我的服务器断电，lucene索引损坏。我运行了IndexChecker，但失败了：

java -cp /home/dthoai/programs/paesia/checker/lucene-core-3.5.0.jar -ea:org.apache.lucene... org.apache.lucene.index.CheckIndex /mnt/peda/paesia/index -fix

如何修复我的lucene索引？

看起来主目录文件已损坏。这可能意味着在执行提交时发生了断电

如果是这种情况，这意味着目录中可能存在较旧的段文件，并且引用的段仍然存在且有效。如果存在此类文件，请尝试删除损坏的

段\u ls0l

文件，并查看：

• Lucene是否打开了索引
• 您丢失了哪些数据

否则，在Lucene用户邮件列表中会有一些线程讨论重新生成段文件

在进行任何修改之前，请确保备份您的目录。

我解决了损坏的lucene索引，这是jpountz先生的答案
