Building a Custom Exporter

You can extend the default implementation of the Writer class using the IoCKernel in Global.asax on the Bootstrapper_Bootstrapped method.

using System;
using Hawksearch.SDK;
using Hawksearch.SDK.Export.IO;
using SitefinityWebApp.Search;
using Telerik.Sitefinity.Abstractions;

namespace SitefinityWebApp
{
    public class Global : System.Web.HttpApplication
    {
        protected void Application_Start(object sender, EventArgs e)
        {
            Bootstrapper.Bootstrapped += this.Bootstrapper_Bootstrapped;
        }

        private void Bootstrapper_Bootstrapped(object sender, EventArgs e)
        {
            IocKernel.Kernel.Rebind<IWriter>().To<CustomWriterClass>();
        }
    }
}

Add External Data to the Index

Add additional Field to single V4L Document:

Create a class (CustomWriterClass).
Inherit the Writer class from the Hawksearch.SDK.Export.IO
Override the method AppendAttribute() and add your custom field.

using System.Collections.Generic;
using System.Text;
using Hawksearch.SDK.Export.IO;
using Hawksearch.SDK.Indexing;

namespace HawksearchApp.Controllers
{
    public class CustomWriterClass : Writer
    {
        protected override void AppendAttribute(string fieldName, List<string> fieldValues, SubmitDocument submitDoc, ref StringBuilder attributesSb)
        {
            var attributesLineTemplate = "{0}\t{1}\t{2}";
            var id = submitDoc.IdentityField["IdentityField"];

            attributesSb.AppendLine(
                    string.Format(
                        attributesLineTemplate,
                        id,
                        "your-custom-field-name",
                        "your-custom-field-value"));

            base.AppendAttribute(fieldName, fieldValues, submitDoc, ref attributesSb);
        }
    }
}
