I am adding a custom field to my index, so I can search through tagged multi-node tree picker content. The below works fine, however it appears to be triggered before the content is published making the field content out of date.

public class AppEvents : IApplicationEventHandler
{
    public void OnApplicationStarted(UmbracoApplicationBase umbracoApplication, ApplicationContext applicationContext)
    {

        var helper = new UmbracoHelper(UmbracoContext.Current);

        ExamineManager.Instance.IndexProviderCollection[GlobalSettings.Indexer.MediaTileIndexer].GatheringNodeData
            += (sender, e) => ExamineEvents.GatheringContentData(sender, e, helper);
    }
}

 public static class ExamineEvents
{
    public static void GatheringContentData(object sender, IndexingNodeDataEventArgs e, UmbracoHelper helper, List<string> docTypes)
    {
        var content = helper.TypedContent(e.NodeId);
        if (content != null){

            var text = content.GetPropertyValue<string>("text");
            // content is not current.

        }
    }
}

As an aside, I've noticed there hasn't been much noise on google about this approach since 2015. Feeling like I'm missing a trick. I'm using 7.71
