Request for Refactoring Repository with Elastic.Clients.Elasticsearch

[patelakash50]

Hi Henrique Mauri,

Thank you for sharing your sample code; it's been incredibly helpful for me!

We've recently upgraded our project to .NET 9 and noticed that NEST is now deprecated. To align with the latest standards, we kindly request you to refactor the repository to use the Elastic.Clients.Elasticsearch package. Creating this in a new branch or as a separate project would make it easier to compare the changes and adapt them to our use case.

Your updated code would be highly valuable for those transitioning to the newer Elastic client libraries.

Thanks in advance for considering this!
