Goal

The purpose of this article is to show you how to create your own Indexer and how to use it instead of the default one.

Overview

In order to define your custom Hawksearch Indexer which will be used instead of the default one, there are 2 approaches - create your own indexer class which implements the IHawksearchIndexer interface or inherit from the existing Indexer class and override your desired functionality. You also need to register the new indexer class within Kentico’s CMS.Core.Service container.

Steps to creating your own indexer

1. Either create your own class which implements Hawksearch.Kentico.Xperience.CMS.Services.Indexing.Contracts.IHawksearchIndexer or inherit from Hawksearch.Kentico.Xperience.CMS.Services.Indexing.Indexer.

2. Implement your custom logic.

3. Create a new module to contain the initialization code: https://docs.xperience.io/custom-development/creating-custom-modules/initializing-modules-to-run-custom-code

4. In the module’s OnPreInit method, register your new indexer class. Here CustomIndexer is assumed to be your indexer class, so replace it with your own class name:
   

   Code Block
   protected override void OnPreInit() { base.OnPreInit(); CMS.Core.Service.Use<IHawksearchIndexer>(new CustomIndexer()); }
