Goal

The purpose of this article is to show you how to add additional information to a document. For the purpose of this tutorial, it will be assumed that you have inherited the Hawksearch.Kentico.Xperience.CMS.Services.Indexing.Indexer class and want to extend its behavior instead of writing your own Indexer from scratch.

Steps to adding additional information to a document

  1. Override the GetDocuments method and write out your custom logic. For example the following snippet adds a custom field called “CustomEventItemFieldName” on all Documents which have a field with a name “ContentType” which has a value of “Event”.

    Code Block
            public override IEnumerable<SubmitDocument> GetDocuments(IEnumerable<FieldMappingInfo> fieldMappings, IEnumerable<string> identifiers = null)
        {
            var documents = base.GetDocuments(fieldMappings, identifiers);

            foreach (var document in documents)
            {
                if (document.Fields.Any(a => a.Name == "ContentType" && a.Values.Any(b => b == "Event")))
                {
                    document.Fields.Add(new SubmitField
                    {
                        Name = "CustomEventItemFieldName",
                        Values = new List<string>
                        {
                            "CustomEventItemValue"
                        }
                    });
                }
            }

            return documents;
        }
