To successfully test DEX search configurations, complete the following prerequisites.
Verify that you have completed the following tasks before testing your DEX search
        configuration:
- Ensure that a staging DSS has been created. See  Installing New DSS Instances for
          details.
- Update InSite Search NuGet packages to the latest release. See  Updating DEX Packages and Schemas for details.
- In Visual Studio, rebuild your DSS project to include the new DEX packages.
- Import the latest schemas into . See  Updating DEX Packages and Schemas for details.
- Set Search.config and other search-specific configuration files.
          See  InSite Search Reference Resources for details.
- Create the appropriate DEX search component. See  Creating DEX Search Components
          for details.Note For this test, the DEX - Ingeniux Search - Local component will be
            used. 
- In Internet Information Services (IIS), recycle the DSS application pool.
- Delete any main index files in the App_Data\luceneindex
          folder.Note The App_Data\LuceneIndex folder structure is present only after the
            initial generation of the main search index files. See   Indexing for
            details. 
- Run a full publish, which includes the new Ingeniux DEX search component.
- In your browser, enter an address to your DSS website Sample URL: http://website.com/dss/x3.xmlNote Any address to the DSS website will trigger the indexing of content and
            the generation of indexing files in App_Data\LuceneIndex. This
            process may take a few minutes to complete, so you may receive inaccurate search results
            in the intervening time. 
- Verify that indexing files have populated the App_Data\LuceneIndex
          folder on your DSS server. In particular, check the Date modified values of the
          index files to ensure that they were created as a result of your last publish.
Next Steps:  Once you have all of the prerequisite tasks completed and indexes have populated the
        App_Data\LuceneIndex folder, you are ready to test DEX. See  DEX Test Procedure for details.
