重建搜索索引时出现 Sitecore 错误

Question

我遇到了一个有趣的问题。当我想重建我的一个搜索索引时出现以下错误。

它以前工作过很多次，但现在失败了。其他索引，如 master、web ... 工作正常。

我使用的是 Sitecore.NET 7.0 (rev. 140408)，错误是：

Job started: Index_Update_IndexName=BlablaSearchIndex|#Exception: System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.OverflowException: Arithmetic operation resulted in an overflow.

有人可以帮我吗？或者只是提示我应该在哪里找到解决方案？

非常感谢。

我已经看到 Lucene 索引多次损坏并在重建期间导致类似问题。您可以尝试删除相关目录（默认情况下会在 Data/Indexes 文件夹中）并再次触发重建。
