Umbraco Lucene索引设备未准备好

Question

所以我在windows共享主机上的Umbraco 7实例上得到一个异常。似乎在任意一段时间后，Lucene索引(我不直接调用其API)出现问题，应用程序进入错误状态，直到我刷新应用程序池。如有任何帮助，我将不胜感激。

Azure网站使用远程文件系统，这可能会对Lucene造成一些破坏，我们已经看到这个错误很多次了。我只能假设Godaddy也为他们的IIS网站使用远程文件服务器。

基本上，解决方案是在本地临时asp.net存储上运行Umbraco lucene索引。在最新版本的Umbraco(7.2.8+)中，该功能被内置到核心中，您可以为索引器和搜索器使用LocalOnly配置标志，例如:

  <add name="InternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"
       supportUnpublished="true"
       supportProtected="true" 
       analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net"
       useTempStorage="LocalOnly"/>
  <add name="InternalSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine"
       analyzer="Lucene.Net.Analysis.WhitespaceAnalyzer, Lucene.Net" 
       useTempStorage="LocalOnly"/>

如果你使用的是旧版本的Umbraco，你可以使用一个名为TempStorage的自定义库:https://github.com/Shazwazza/UmbracoExamine.TempStorage
