Add Index Settings

Content Search components require that you register Tiles which you are going to use.

Add two index files:

1. <Solution>.Environments\ALL\App_Config\Include\<Solution>\ContentSearch.Tiles.sitecore_master_index.config  
   Each Tile must be registered as a separate field with parameters:
   fieldName - The Tile name in lowercase with suffix " tile" to prevent collision with content fields.
   tileName - The Tile name associated with a content item (case insensitive).
   siteContext - The site context required to build correct URLs. 

   ContentSearch.Tiles.sitecore_master_index.config

   <configuration xmlns:patch="http://www.sitecore.net/xmlconfig/">
     <sitecore>
       <contentSearch>
         <indexConfigurations>
           <scoreMasterConfiguration type="Sitecore.ContentSearch.LuceneProvider.LuceneIndexConfiguration, Sitecore.ContentSearch.LuceneProvider">
             <fields hint="raw:AddComputedIndexField">
               <field fieldName="default tile" tileName="default" siteContext="MySite" returnType="System.String">Score.Custom.Indexing.PreviewField, Score.Custom</field>
               <field fieldName="search result tile" tileName="Search Result" siteContext="MySite" returnType="System.String">Score.Custom.Indexing.PreviewField, Score.Custom</field>
               <field fieldName="autocomplete tile" tileName="Autocomplete" siteContext="MySite" returnType="System.String">Score.Custom.Indexing.PreviewField, Score.Custom</field>
             </fields>
           </scoreMasterConfiguration>
         </indexConfigurations>
       </contentSearch>
     </sitecore>
   </configuration>

2. <Solution>.Environments\ALL\App_Config\Include\<Solution>\ContentSearch.Tiles.sitecore_web_index.config
   Each Tile is required to be registered as a separated field with parameters:
   fieldName - The Tile name in lowercase with suffix " tile" to prevent collision with content fields.
   tileName - The Tile name associated with a content item (case insensitive).
   siteContext - The site context required to build correct URLs.
