Goal

This article provides information on how to extend the indexing logic for Hawksearch Elastic

Prerequisite

Installed Connector - Installing the Connector

Building a Custom Search Service

Create a custom search service class and inherit from HawksearchService.
Change the Search Service implementation from Sitefinity’s Advanced Settings (your-website-domain/Sitefinity/Administration/Settings/Advanced) -
1. Navigate to:
  Administration → Settings → Advanced Settings → Search → Search Services → Hawksearch In TypeName field enter your custom search service type name (the namespace plus the name of the class e.g. SitefinityWebApp.Search.CustomSearchService).

Add External Data to the Index

Add additional Fields to the index

The string type of the field in the code bellow is used as an example.

using Hawksearch.Search;
using System.Collections.Generic;
using System.Linq;
using Telerik.Sitefinity.Services.Search;

namespace SitefinityWebApp.Search
{
    public class CustomSearchService : HawksearchService
    {
        public override void CreateIndex(string sitefinityIndexName, IEnumerable<IFieldDefinition> fieldDefinitions)
        {
            var newFieldDefinition = Telerik.Sitefinity.Abstractions.ObjectFactory.Resolve<IFieldDefinition>();

            newFieldDefinition.Name = "your-custom-field-name";
            newFieldDefinition.Type = typeof(string);

            var definitions = fieldDefinitions.ToList();
            definitions.Add(newFieldDefinition);

            base.CreateIndex(sitefinityIndexName, definitions);
        }
    }
}

2. Add additional Fields to Elasticsearch Document

using Hawksearch.Search;
using System.Collections.Generic;
using Telerik.Sitefinity.Services.Search.Data;
using Telerik.Sitefinity.Services.Search.Model;
using Telerik.Sitefinity.Services.Search.Publishing;

namespace SitefinityWebApp.Search
{
    public class CustomSearchService : HawksearchService
    {
        public override void UpdateIndex(string name, IEnumerable<IDocument> documents)
        {
            var documentList = new List<IDocument>();

            foreach (var document in documents)
            {
                var fields = new List<IField>();
                fields.AddRange(document.Fields);

                var newField = new Field
                {
                    Name = "your-custom-field-name",
                    Value = "your-custom-field-value"
                };

                fields.Add(newField);

                var modifiedDocument = new Document(fields, document.IdentityField.Name);

                documentList.Add(modifiedDocument);
            }

            base.UpdateIndex(name, documentList);
        }
    }
}
