Hi all,

I have a large number of fields across different document types that should be indexed in my custom indexer but Examine is not indexing them correctly.

It is very strange as the Umbraco back end suggests the fields are being indexed (as shown above - visitedCities, visitedCountries) however when I run the following code and look for the key "visitedCities" I get a key not found exception.

public static class ExamineEvents
    {
        public static void GatheringContentData(object sender, IndexingNodeDataEventArgs e, UmbracoHelper helper)
        {
            IPublishedContent content = null;
            IPublishedContent homepage = null;

            try
            {
                content = helper.TypedContent(e.NodeId);
                homepage = content.AncestorOrSelf("homepage");
                e.Fields.Add("siteNode", homepage.Id.ToString());
            }
            catch (System.NullReferenceException ex)
            {
                if (e.Fields["level"] != "1")
                {
                    IContentService cs = ApplicationContext.Current.Services.ContentService;
                    IContent[] unpublishedPageAncestors = cs.GetAncestors(e.NodeId).ToArray();
                    if (unpublishedPageAncestors.Where(x => x.ContentType.Alias.ToLower() == "homepage").Count() == 1)
                    {
                        int id = unpublishedPageAncestors.First().Id;
                        e.Fields.Add("siteNode", id.ToString());
                    }
                }
                else
                {
                    e.Fields.Add("siteNode", e.Fields["id"]);
                }
            }
            catch (Exception ex)
            {
                // Do Nothing
            }

            if (e.Fields["nodeTypeAlias"] == "package")
            {
                try
                {
                    if (!e.Fields["visitedCities"].IsNullOrWhiteSpace())
                    {
                        List<string> countries = new List<string>();
                        List<string> cities = e.Fields["visitedCities"].Split(',').ToList();
                        foreach (string city in cities)
                        {
                            IEnumerable<IPublishedContent> nodes = homepage.Descendants("city").Where(x => x.GetPropertyValue<string>("cityCode") == city);
                            if (nodes.Count() > 0)
                            {
                                try 
                                {           
                                    IPublishedContent page = nodes.First();
                                    IPublishedContent country = page.Ancestor("country");
                                    countries.Add(country.GetPropertyValue<string>("countryCode"));
                                }
                                catch (Exception)
                                {
                                }
                            }
                        }

                        string csv = String.Join(",", countries.Distinct().ToArray());
                        e.Fields["visitedCountries"] = csv;

                    }
                }
                catch (Exception ex)
                {

                }
            }
        }
    }

Why is examine not indexing these fields correctly and how can I force it to do so?

By default, Umbraco seems to index all custom fields but some it just randomly ignores. I have tried explicitly adding the fields that are missing to the ExamineIndex.config file using the IndexUserFields field however this then causes all other custom fields to be ignored and it still fails to index the fields I have specified.
