Sitecore 7搜索索引問題

Question

我想限制Sitecore 7中的搜索索引只掃描內容樹的一個節點。

目前的結構是這樣的：

• Sitecore的
  • 內容
    • BaseNode
    • $公司節點

該索引是索引BaseNode & $Company Node，但我只希望它索引$Company Node。

我在Sitecore.ContentSearch.config，SitecoreContentSearch.Lucene.DefaultIndexConfiguration.config，Sitecore.ContentSearch.Lucene.Index.Master和Sitecore.ContentSearch.LuceneIndex.Web.config更新默認/sitecore/content路徑。當我將<root>元素更新爲/sitecore/content/$CompanyNode時，我嘗試重建索引時出現以下異常。

任何想法，我需要做的，以限制Lucene索引一些項目，而不是一切？

我相信你正在嘗試修改Master Lucene索引文件。我相信最終會破壞很多事情，我會建議你創建一個新的Lucene索引文件。

如果你要創建一個新的指標：在你的APP_CONFIG /地方該指數包含的文件夾

Sitecore.ContentSearch.Lucene.Index.Alexander.config

在這種配置設置爬蟲搜索爲您的節點。

<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> 

上述索引將索引該節點下的所有內容。在C＃中，您可以輕鬆地使用此方法調用該方法。

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(); 
    } 

您還可以重建索引，並確認它們是由進入Sitecore的工作 - >控制面板 - >索引 - >索引管理器。這樣做後，你應該看到索引。

另一個編輯： 您也可以在內容樹中的該項下執行您的C＃搜索，並僅使用Web數據庫。

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 
    } 
    }
