Great Ismail. Wonder-baa indeed.

Here's my impl. Couldn't get a handle on an UmbracoHelper to lookup publishedcontent instead (UmbracoContext.Current is null at this time), but here's my code for anyone wanting to take or review ;)

public class AppStartupHandler : ApplicationEventHandler
{
    protected override void ApplicationInitialized(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {
        ExamineManager.Instance.IndexProviderCollection["PostsIndexer"].GatheringNodeData += ExamineEvents_GatheringNodeData;
    }

    public class ImageData
    {
        public string src { get; set; }
    }

    private void ExamineEvents_GatheringNodeData(object sender, IndexingNodeDataEventArgs e)
    {
        if (e.IndexType != IndexTypes.Content) return;

        var fields = e.Fields;
        var searchableFields = new Dictionary<string, string>();
        var mediService = ApplicationContext.Current.Services.MediaService;
        foreach (var field in fields)
        {
            switch (field.Key)
            {
                case "postImage":
                    var media = mediService.GetById(int.Parse(field.Value));

                    var imageUrl = media == null
                        ? null
                        : JsonConvert.DeserializeObject<ImageData>(media.GetValue<string>("umbracoFile")).src;

                    searchableFields.Add("postImageUrl", imageUrl);
                    break;
            }
        }

        foreach (var fld in searchableFields)
        {
            e.Fields.Add(fld.Key, fld.Value);
        }
    }
}

Index config:

 <IndexSet SetName="PostsIndexSet" IndexPath="~/App_Data/TEMP/ExamineIndexes/{machinename}/Posts/">
    <IndexAttributeFields>
      <add Name="id" />
      <add Name="nodeName" />
      <add Name="writerName" />
      <add Name="parentID" />
    </IndexAttributeFields>
    <IndexUserFields>
      <add Name="postImage" />
      <add Name="postImageUrl" />
      <add Name="lowResImageUrl" />
      <add Name="postDate" Type="DateTime" />
      <add Name="title" />
      <add Name="categories" />
      <add Name="html" />
      <add Name="videoHtml" />
      <add Name="youtubeId" />
    </IndexUserFields>
    <IncludeNodeTypes>
      <add Name="post"/>
    </IncludeNodeTypes>
  </IndexSet>

Alastair,

There is a way round that null issue on umbracohelper then you dont need media service and the extra db calls that will entail:

public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {

        var indexer = (UmbracoContentIndexer)ExamineManager.Instance.IndexProviderCollection["ExternalIndexer"];

        var helper = new UmbracoHelper(UmbracoContext.Current);

        ExamineManager.Instance.IndexProviderCollection["ExternalIndexer"].GatheringNodeData += (sender, e) => ExternalIndexerGatheringNodeData(sender,e,helper);

                }

then make a modification to the method signature:

 private void ExternalIndexerGatheringNodeData(object sender, IndexingNodeDataEventArgs e, UmbracoHelper helper)
    {
        if (e.IndexType == IndexTypes.Content)
        {
            // We can then search using languge root node
            e.Fields.Add("SearchablePath", e.Fields["path"].Replace(",", " "));

            // Make tags searchable too
            if (e.Fields.ContainsKey("tags"))
            {
                e.Fields.Add("SearchableTags", e.Fields["tags"].Replace(",", " "));
            }

            ExamineHelper.AddAllFieldsToContentField(e,helper);
        }
    }

Regards

Ismail
