Search: a new era

Search: a new era

Search is not just traditional TF/IDF any more but the current trend of machine learning and models has opened another dimension for search.

This talk gives an overview of:

  • “Classic” search and its limitations
  • What is a model and how can you use it
  • How to use vector search or hybrid search in Elasticsearch
  • Where OpenAI’s ChatGPT or similar LLMs come into play to with Elastic

The main demo covers how to generate embeddings from a music and then use the techniques we learned to propose the most probable version of it when we hum a song 🎶🎸🎻.

Search: a new era

Abstract

Search is not just traditional TF/IDF any more but the current trend of machine learning and models has opened another dimension for search.

This talk gives an overview of:

* “Classic” search and its limitations
* What is a model and how can you use it
* How to use vector search or hybrid search in Elasticsearch
* Where OpenAI’s ChatGPT or similar LLMs come into play to with Elastic

The main demo covers how to generate embeddings from a music and then use the techniques we learned to propose the most probable version of it when we hum a song 🎶🎸🎻.

La recherche à l'ère de l'IA

La recherche ne se contente plus de l’approche maintenant traditionnelle basée sur la fréquence des termes (TF/IDF ou BM25) mais plus sur la tendance actuelle du machine learning où les nouveaux modèles ont ouvert une nouvelle dimension pour la recherche.

Cette conférence donne un aperçu de :

  • La recherche “Classique” et ses limitations
  • Qu’est qu’un modèle de machine learning et comment vous pouvez l’utiliser
  • Comment utiliser la recherche vectorielle ou la recherche hybride dans Elasticsearch
  • Comment ChatGPT d’OpenAI ou les “large language models” (LLMs) similaires viennent jouer naturellement avec Elastic

La démo principale montre comment générer des embeddings à partir de musiques puis comment trouver la musique qui s’approche le plus d’une musique que nous fredonnons 🎶🎸🎻.

Details

I discovered Elasticsearch project in 2011. After contributed to the project and created open source plugins for it, David joined elastic the company in 2013 where he is Developer and Evangelist. He also created and still actively managing the French spoken language User Group. At elastic, he mainly worked on Elasticsearch source code, specifically on open-source plugins. In his free time, he likes talking about elasticsearch in conferences or in companies (Brown Bag Lunches AKA BBLs ). He is also author of FSCrawler project which helps to index your pdf, open office, whatever documents in elasticsearch using Apache Tika behind the scene.

Who am I?

Developer | Evangelist at elastic and creator of the Elastic French User Group . Frequent speaker about all things Elastic, in conferences, for User Groups and in companies with BBL talks . In my free time, I enjoy coding and deejaying as DJ Elky , just for fun. Living with my children in Cergy, France.
