我正在更改我的代码以使用旧 Lucene 方式的 Sitecore.Search。为此，我使用了ADC 模块中的爬虫。我目前没有使用搜索器，只是模块中的爬虫（尽管我们希望在稍后阶段更改为它）。
我设法让索引和搜索功能在我的 CM 环境中完美运行，但是当我尝试重建时，CD 环境不断给出以下错误：

找不到配置节点：databases/database[@id='core']。

我正在运行以重建搜索索引的代码在 CD 上是：

foreach (var options in from ListItem item in cblIndexes.Items 
                        where item.Selected           
                        select new JobOptions("RebuildSearchIndex", "index", global::Sitecore.Client.Site.Name, new Builder(item.Value), "Rebuild") { AfterLife = TimeSpan.FromMinutes(1.0) })
           {
               JobManager.Start(options);
           }

在 CM 上运行此代码可以正常工作。

当解决方案仍在 Sitecore 6.3.1 上（我们升级到 Sitecore 6.5 update 5）时，我已经浏览了暂存指南Core，并删除了对数据库的所有引用。

当我转到 CD 上的 ShowConfig 页面并查找“核心”时，我没有找到任何结果。AppSettings.config、ConnectionStrings.config 或我拥有的任何其他配置文件中也没有对 Core 数据库的引用。据我发现，我也没有引用硬编码的核心数据库（否​​则我会在此之前遇到问题）。

我无法弄清楚核心数据库将被引用到哪里。

我不认为该问题与您的索引配置特别相关。查看您的堆栈跟踪，当您的搜索爬虫尝试获取分隔字段（多列表、树列表等）的链接（引用）时，异常确实源于 Sitecore.Web.UI.HtmlControls.Data.LookupSources.GetDatabase 方法。 .)。

   at Sitecore.Configuration.Factory.GetDatabase(String name)
   at Sitecore.Web.UI.HtmlControls.Data.LookupSources.GetDatabase(String source)
   at Sitecore.Data.Fields.CustomField.GetDatabase()
   at Sitecore.Data.Fields.DelimitedField.ValidateLinks(LinksValidationResult result)
   at Sitecore.Links.ItemLinks.AddLinks(Field field, List`1 links, ItemLinkState linkState)
   at Sitecore.Links.ItemLinks.GetLinks(ItemLinkState linkState, Boolean allVersions, Boolean includeStandardValuesLinks)
   at Sitecore.Search.Crawlers.DatabaseCrawler.GetItemLinks(Item item)

使用反射器，我们可以查看 Sitecore.Data.Fields.CustomField.GetDatabase() 方法，如果关联的字段在其“源”字段中有值，该方法将调用 LookupSources.GetDatabase 方法。LookupSources.GetDatabase 方法尝试分析“源”字段以确定在哪个数据库中查询相关分隔字段中的源项。某些源字段可以使用“db=”参数显式设置要查询源项的数据库。

因此，长话短说，当您<IndexAllFields>true</IndexAllFields>在索引配置中使用时，您的爬虫试图索引的字段之一有一个“源”字段，其中包含对核心数据库的引用。

您将<IndexAllFields />值设置为 false 然后显式包含或排除要索引的字段的解决方案当然是有效的，但如果您想追查问题的根本原因，您可能必须查看“源”字段。

它似乎与<IndexAllFields>配置中的相关。我的第二个索引将此设置为 true。我将它设置为 false，IncludeFields并且ExcludeFields它现在正在成功构建。

不过，我仍然想知道为什么它会抛出该错误，因为Core数据库之前已被删除。可能是标准字段？
