Lucene 索引的问题已经有一段时间了。

基本上，当我们尝试发布内容时，索引通常会抛出如下错误：

2020-01-13 22:22:38,068 [P36840/D2/TLucene Merge Thread #0] ERROR Umbraco.Core.UmbracoApplicationBase - Unhandled exception in AppDomain (terminating)
Lucene.Net.Index.MergePolicy+MergeException: Exception of type 'Lucene.Net.Index.MergePolicy+MergeException' was thrown. ---> System.IO.IOException: read past EOF
   at Lucene.Net.Index.IndexWriter.HandleMergeException(Exception t, OneMerge merge)
   at Lucene.Net.Index.IndexWriter.Merge(OneMerge merge)
   at Lucene.Net.Index.ConcurrentMergeScheduler.DoMerge(OneMerge merge)

   at System.Threading.ExecutionContext.Run(ExecutionContext executionContext, ContextCallback callback, Object state)
   at System.Threading.ThreadHelper.ThreadStart()

结果，我们进入Secure Connection Failed公共站点，内容正在保存但未包含在缓存中，因此它不会显示在网站上。

然后我们无法访问检查管理仪表板来重新启动索引。

错误有时也像这样：

 2019-12-30 14:49:14,895 [P18524/D2/T28] ERROR Umbraco.Core.UmbracoApplicationBase - Unhandled exception in AppDomain (terminating)

   at System.Threading.TimerQueueTimer.CallCallbackInContext(Object state)
   at System.Threading.ExecutionContext.RunInternal(ExecutionContext executionContext, ContextCallback callback, Object state, Boolean preserveSyncCtx)

在这种情况下，发布内容实际上变得无效。

知道是什么原因吗？以及如何解决？我可以看到索引已损坏，但为什么呢？

我检查了几个类似的问题，例如：

Umbraco 索引错误填充日志

https://issues.apache.org/jira/browse/LUCENENET-527但它们都不是我们的情况 - 我看不到任何 0kB 段文件。

编辑

该错误使整个网站崩溃，导致安全连接失败错误，并且在尝试对内容执行保存时发生（无论是通过 CMS 还是前端站点）。
