c# – Sitecore 7搜索索引问题

我想将Sitecore 7中的搜索索引限制为仅扫描内容树的一个节点.

目前结构如下：

> sitecore

>内容

> BaseNode
> $公司节点

索引正在索引BaseNode和amp; $Company Node,但我只想让它为$Company Node编制索引.

我更新了Sitecore.ContentSearch.config,SitecoreContentSearch.Lucene.DefaultIndexConfiguration.config,Sitecore.ContentSearch.Lucene.Index.Master和Sitecore.ContentSearch.LuceneIndex.Web.config中的默认/ sitecore / content路径.当我更新< root>要指向/ sitecore / content / $CompanyNode的元素,当我尝试重建索引时,我收到以下异常.

任何想法,我需要做什么来限制Lucene只是索引一些项目,而不是一切？

解决方法:

我相信您正在尝试修改Master Lucene Index文件.我相信最终会破坏很多东西,我建议你创建一个新的Lucene索引文件.

如果要创建新索引：将此索引放在App_Config / Include文件夹中

Sitecore.ContentSearch.Lucene.Index.Alexander.config

在该配置中,您将爬网程序设置为搜索您的节点.

<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>

上面的索引将索引该节点下的所有内容.
在C#中,你可以轻松地调用它.

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();
   }

您还可以通过进入Sitecore重建索引并验证它们是否正常工作 – >控制面板 – >索引 – >索引管理器.完成后,您应该看到索引.

另一个编辑：
您也可以在内容树中的该项下面执行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
     }
  }
