Sitecore - 未定义根项目

Question

我在尝试使用 TDS 进行部署时遇到了以下错误。我不相信有任何自定义索引。我查看了以下链接并清除了我的 \Data\Indexes 文件夹。

Sitecore Index error - Root Item Not defined

什么会导致这个错误？

这也是我收到错误的网址：http://<hostname>/sitecore

如果您浏览到此页面 http://[yourhostname]/sitecore/admin/showconfig.aspx

搜索 index 元素的任何实例并检查 <Root>path here</Root> 节点路径是否确实存在于您的内容树中

查看默认索引示例

<index id="system" type="Sitecore.Search.Index, Sitecore.Kernel">
<param desc="name">$(id)</param>
<param desc="folder">__system</param>
<Analyzer ref="search/analyzer"/>
<locations hint="list:AddCrawler">
<core type="Sitecore.Search.Crawlers.DatabaseCrawler,Sitecore.Kernel">
<Database>core</Database>
<Root>/sitecore/content</Root>
<include hint="list:IncludeTemplate">
<application>{EB06CEC0-5E2D-4DC4-875B-01ADCC577D13}</application>
</include>
<Tags>application</Tags>
<Boost>2.0</Boost>
</core>
<core-controlpanel type="Sitecore.Search.Crawlers.DatabaseCrawler,Sitecore.Kernel">
<Database>core</Database>
<Root>/sitecore/content/applications/control panel</Root>
<include hint="list:IncludeTemplate">
<taskoption>{BDB6FA46-2F76-4BDE-8138-52B56C2FC47E}</taskoption>
</include>
<Tags>taskoption</Tags>
<Boost>1.9</Boost>
</core-controlpanel>
<master type="Sitecore.Search.Crawlers.DatabaseCrawler,Sitecore.Kernel">
<Database>master</Database>
<Tags>master content</Tags>
</master>
</locations>
</index>

一旦您更正了任何无效的 Root 值，该站点应该会再次运行。

问题原因

此问题通常发生在 Sitecore lucene 索引 已声明但它所引用的<Root> 不在数据库中时。

注意：如果索引目标的数据库是 web，这可能是因为您没有 published 项目。

问题修复

因为您无法访问 Sitecore 桌面，您必须注释掉导致问题的索引。如果您不知道是哪一个，则必须使用简单的旧试验和错误，因为 sitecore 不会告诉您。

要查看您在系统中声明的所有索引，请转到http://[yourhostname]/sitecore/admin/showconfig.aspx 并搜索<index。这是 App_Config 中声明的所有配置的组合。

索引如下所示：

<index id="MyIndexId" type="Sitecore.Search.Index, Sitecore.Kernel">

找到罪魁祸首后，将其注释掉，然后在 Sitecore 中创建或部署缺失的根项目。完成后，重新添加索引。
