Using FIND to index contents of a block added to page as a Conten

Using FIND to index contents of a block added to page as a ContentReference

We are using find to retrieve some content based on search text. I can index content blocks on my page that are added to a Content Area if they are marked with the [IndexInContentAreas] attribute, but it doesn't seem to index content blocks that are added as ContentReference type (see sample below). These blocks are also decorated with the [IndexInContentAreas] attribute but don't return results.

How do I get FIND to index the contents of the block in a ContentReference?

[Required]
[Display(
    Name = "Fund Profile",
    Description = "Content block with fund details",
    Order = 10)]
[AllowedTypes(typeof(FundTemplateBlock))]
public virtual ContentReference FundTemplate { get; set; }

I guess you would need to add an extension method for your content, something like

public static FundTemplateBlock FundBlock(this MyContent content)

{

//Load and return your block

}

and include this in your convention

Hi Eric,

For that, you need to do some level of customization. Create an IniitializationModule and add you custom property to index like this

[InitializableModule]
[ModuleDependency(typeof(IndexingModule))]
public class SearchInitialization : IInitializableModule
{
    public void Initialize(InitializationEngine context)
    {
        SearchClient.Instance.Conventions
            .ForInstancesOf<MyPage>()
            .IncludeField(x => x.FundTemplateContent());
    }
}

Then, in your method, FundTemplateContent() get your block from ContentReference property and return content to index it. (see below example)

public static string FundTemplateContent(this MyPage page)
{
    var fundTemplate = string.Empty;
    if (page?.FundTemplate == null || ContentReference.IsNullOrEmpty(page.FundTemplate))
        return fundTemplate;

    var content = ContentLoader.Service.Get<FundTemplateBlock>(page.FundTemplate);
    if (content != null)
    {
        fundTemplate = content.Property1; //string property
        fundTemplate += content.Property2; //string property
    }
    return fundTemplate;
}

Note: Above code is not completely tested. This is a sample code :)

Hope this will help.

This worked. Thanks. Made a couple of small changes to get it working. See working code below.

    [InitializableModule]
    [ModuleDependency(typeof(IndexingModule))]
    public class SearchInitialization : IInitializableModule
    {
        public void Initialize(InitializationEngine context)
        {
            SearchClient.Instance.Conventions
                .ForInstancesOf<FundDetailsPage>()
                .IncludeField(x => x.FundTemplateContent(x));
        }

        public void Uninitialize(InitializationEngine context)
        {}
    }

And my FundTemplateContent method inside my FundDetailsPage

  public string FundTemplateContent(FundDetailsPage page)
  {
      var fundTemplate = string.Empty;
      if (page?.FundTemplate == null || 
          ContentReference.IsNullOrEmpty(page.FundTemplate))
          { return fundTemplate; }

      var contentLoader = ServiceLocator.Current.GetInstance<IContentLoader>();
      var content = contentLoader.Get<FundTemplateBlock>(page.FundTemplate);

      if (content != null)
      {
          fundTemplate = content. ///string field;
          ... //all other string fields
      }

      return fundTemplate;
  }
