我自己在项目中实现了对media folder中pdf文件的search功能，使用的依然是Umbraco中的 ExternalSearcher, Index 也是 UmbracoContentIndexer

ExamineSettings.config 如下：

<Examine>

  <ExamineIndexProviders>

    <providers>

        <!-- default external indexer, which excludes protected and unpublished pages-->

        <add name="ExternalIndexer" type="UmbracoExamine.UmbracoContentIndexer, UmbracoExamine"/>

    </providers>

  </ExamineIndexProviders>

  <ExamineSearchProviders defaultProvider="ExternalSearcher">

    <providers>

           <add name="ExternalSearcher" type="UmbracoExamine.UmbracoExamineSearcher, UmbracoExamine" />

    </providers>

  </ExamineSearchProviders>

</Examine>

ExamineIndex.config

<ExamineLuceneIndexSets>

  <!-- Default Indexset for external searches, this indexes all fields on all types of nodes-->

  <IndexSet SetName="ExternalIndexSet" IndexPath="~/App_Data/TEMP/ExamineIndexes/{machinename}/External/">

  </IndexSet>

</ExamineLuceneIndexSets>

在代码层面是这样写的：

 internal const string SearcherGeneral = "ExternalSearcher";

  var provider = Examine.ExamineManager.Instance.SearchProviderCollection[SearcherGeneral];

var searchCriteria = provider.CreateSearchCriteria(UmbracoExamine.IndexTypes.Media);

  var filter = searchCriteria.Field("umbracoExtension","pdf").Compile();

   var results = provider.Search(filter);
