Infuriating search not indexing all page string fields


Has anybody had any experience of the Episerver Search not indexing all the text fields in a page? I have a text field in my SitePageData which stubbonly refuses to show up in any searches. I have tried changing it to a XHTMLString to see if that makes any difference, but it does not. The field is updated from a scheduled task which collects all the text data from any blocks within the page. I know that the field is getting updated as the function that populates the fields can also read them out again to a log, with a different parameter.

The site is supposed to go live on 30th Dec so i am a bit worried

Thanks, in advance,

Hi Marshall,

So, I assume you are talking about the built-in Episerver search? It is annoying that it doesn't index everything, but, I think that is on purpose becasue they want people to use Find. Anyway, here is what you do to index custom fields.

First, create an init module:

    public class SearchInitialization : IInitializableModule
        public void Initialize(InitializationEngine context)
            IndexingService.DocumentAdding += CustomizeIndexing;

        public void Uninitialize(InitializationEngine context)
            IndexingService.DocumentAdding -= CustomizeIndexing;

        void CustomizeIndexing(object sender, EventArgs e)
            var addUpdateEventArgs = e as AddUpdateEventArgs;

            if(addUpdateEventArgs == null)
                return; //Document is not being added/updated

            var document = addUpdateEventArgs.Document;

            var page = document.GetContent<IContent>() as PageData;

            if(page != null && page is SitePageData)
                var examplePage = page as SitePageData;
                if(examplePage.YourCustomField != null)
                    document.Add(new Field("CUSTOM_FIELD", examplePage.YourCustomField, Field.Store.NO, Field.Index.ANALYZED));

Here is the extension method GetContent that the variable page is using when getting set:

public static class DocumentHelper
        public static T GetContent<T>(this Document document) where T : IContent
            const string fieldName = "EPISERVER_SEARCH_ID";

            var fieldValue = document.Get(fieldName);

                throw new NotSupportedException(
                    string.Format("Specified document did not have a '{0}' field value", fieldName));

            var fieldValueFragments = fieldValue.Split('|');

            Guid contentGuid;

            if(!Guid.TryParse(fieldValueFragments[0], out contentGuid))
                throw new NotSupportedException(
                    "Expected first part of ID field to be valid GUID");

            return ServiceLocator.Current.GetInstance<IContentLoader>().Get<T>(contentGuid);

Here is an example of a search query using the cutom field:

public void Search(string q)
            var culture = ContentLanguage.PreferredCulture.Name;
            SearchResult = new List<IndexResponseItem>();

            var query = new GroupQuery(LuceneOperator.AND);

            // Only search for pages
            query.QueryExpressions.Add(new ContentQuery<PageData>());

            // Search for keywords in any of te fields specified below (OR condition)
            var keywordsQuery = new GroupQuery(LuceneOperator.OR);

            // Search in default fields
            keywordsQuery.QueryExpressions.Add(new FieldQuery(q));

            // Search in the custom fields
            keywordsQuery.QueryExpressions.Add(new CustomFieldQuery(q, "CUSTOM_FIELD"));


            // The access control list query will remove any pages the user doesn't have read access to
            var accessQuery = new AccessControlListQuery();
            accessQuery.AddAclForUser(PrincipalInfo.Current, HttpContext.Current);

            var fieldQueryResult = SearchHandler.Instance.GetSearchResults(query, 1, 40)
                //.Where(x =>
                //    (x.Culture.Equals(culture) || string.IsNullOrEmpty(x.Culture))
                //    )



Lastly, when you update the field in your scheduled job, update the index:

var contentSearchHandler = ServiceLocator.Current.GetInstance<ContentSearchHandler>();
            contentSearchHandler.UpdateItem(currentPage as IContent);

I hope this helps!
