C# Sitecore 7搜索索引问题

C# Sitecore 7搜索索引问题,c#,.net,sitecore,lucene.net,sitecore7,C#,.net,Sitecore,Lucene.net,Sitecore7,我想限制Sitecore 7中的搜索索引只扫描内容树的一个节点 当前结构如下所示: 站点核心 内容 基本节点 $Company节点 索引正在索引BaseNode和$Company Node,但我只希望它索引$Company Node 我已经更新了sitecore.ContentSearch.config、sitecoretentsearch.Lucene.DefaultIndexConfiguration.config、sitecore.ContentSearch.Lucene.In

我想限制Sitecore 7中的搜索索引只扫描内容树的一个节点

当前结构如下所示:

  • 站点核心
    • 内容
      • 基本节点
      • $Company节点
索引正在索引
BaseNode
$Company Node
,但我只希望它索引
$Company Node

我已经更新了
sitecore.ContentSearch.config
sitecoretentsearch.Lucene.DefaultIndexConfiguration.config
sitecore.ContentSearch.Lucene.Index.Master
sitecore.ContentSearch.LuceneIndex.Web.config
中的默认路径。当我将
元素更新为指向
/sitecore/content/$CompanyNode
时,我在尝试重建索引时遇到以下异常

我需要做些什么来限制Lucene只索引一些项目,而不是所有项目

我相信您正在试图修改主Lucene索引文件。我相信这最终会破坏很多东西,我建议您创建一个新的Lucene索引文件

如果要创建新索引:请将此索引放置在App\u Config/Include文件夹中

Sitecore.ContentSearch.Lucene.Index.Alexander.config

在该配置中,您将爬虫设置为搜索节点

<configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
  <sitecore>
    <contentSearch>
     <configuration type="Sitecore.ContentSearch.LuceneProvider.LuceneSearchConfiguration, Sitecore.ContentSearch.LuceneProvider">
      <indexes hint="list:AddIndex">
       <index id="alexander_search_index" type="Sitecore.ContentSearch.LuceneProvider.LuceneIndex, Sitecore.ContentSearch.LuceneProvider">
        <param desc="name">$(id)</param>
        <param desc="folder">$(id)</param>
        <!-- This initializes index property store. Id has to be set to the index id -->
        <param desc="propertyStore" ref="contentSearch/databasePropertyStore" param1="$(id)" />
        <strategies hint="list:AddStrategy">
          <!-- NOTE: order of these is controls the execution order -->
          <strategy ref="contentSearch/indexUpdateStrategies/onPublishEndAsync" />
        </strategies>
        <commitPolicy hint="raw:SetCommitPolicy">
          <policy type="Sitecore.ContentSearch.TimeIntervalCommitPolicy, Sitecore.ContentSearch" />
        </commitPolicy>
        <commitPolicyExecutor hint="raw:SetCommitPolicyExecutor">
          <policyExecutor type="Sitecore.ContentSearch.CommitPolicyExecutor, Sitecore.ContentSearch" />
        </commitPolicyExecutor>
        <locations hint="list:AddCrawler">
          <crawler type="Sitecore.ContentSearch.LuceneProvider.Crawlers.DefaultCrawler, Sitecore.ContentSearch.LuceneProvider">
            <Database>web</Database>
            <Root>/sitecore/content/$Company Node</Root>
          </crawler>
        </locations>
       </index>
     </indexes>
   </configuration>
  </contentSearch>
 </sitecore>
</configuration>

$(id)
$(id)
网状物
/sitecore/content/$Company节点
上述索引将索引该节点下的所有内容。 在C#中,您可以轻松地将其称为

ContentSearchManager.GetIndex("alexander_search_index").Rebuild();

using (var searchContext = ContentSearchManager.GetIndex("alexander_search_index").CreateSearchContext())
   {
       var result = searchContext.GetQueryable<SearchResultItem>()
           .Where(//Put Query Here);

       //do ForEach if you return multiple and so on.

       if (result != null)
              Context.Item = result.GetItem();
   }
ContentSearchManager.GetIndex(“alexander_search_index”).Rebuild();
使用(var searchContext=ContentSearchManager.GetIndex(“alexander\u search\u index”).CreateSearchContext())
{
var result=searchContext.GetQueryable()
.Where(//将查询放在这里);
//如果返回多个,则执行ForEach,以此类推。
如果(结果!=null)
Context.Item=result.GetItem();
}
您还可以通过进入Sitecore->Control Panel->Indexing->Indexing Manager来重建索引并验证它们是否正常工作。这样做之后,您应该会看到索引

另一编辑: 您还可以在内容树中的该项目下执行C#搜索,并仅使用web数据库

 Item bucketItem = //Code to get $Company Node as a Sitecore Item
  //Probably Sitecore.Context.Database.GetItem("Guid for $Company Node")

 using (var searchContext = ContentSearchManager.GetIndex(bucketItem as      IIndexable).CreateSearchContext())
  {
     try
     {
          var result = searchContext.GetQueryable<SearchResultItem>().Where(x => x.Name == itemName).FirstOrDefault();
             if (result != null)
                 Context.Item = result.GetItem();
     }
     catch (Exception)
     {
         //Do something
     }
  }
Item bucketItem=//将$Company节点作为Sitecore项获取的代码
//可能是Sitecore.Context.Database.GetItem(“用于$Company节点的Guid”)
使用(var searchContext=ContentSearchManager.GetIndex(bucketItem作为IIndexable.CreateSearchContext())
{
尝试
{
var result=searchContext.GetQueryable()。其中(x=>x.Name==itemName.FirstOrDefault();
如果(结果!=null)
Context.Item=result.GetItem();
}
捕获(例外)
{
//做点什么
}
}

请标记正确答案或提供更多信息。:)嗨,安德鲁,我正在与另一个资源合作收集更多信息。我想我们会实施你的解决方案,但现在这个任务被卡在了“等待”任务列表上。
