Semantic search excellence: Getting started with Search AI

Jeff Vestal

Principal GenAI Specialist

Elastic

Join us to learn how to build a modern Search AI experience using Elasticsearch. In this hands-on session, you'll set up an Elastic Cloud Serverless project, crawl real-world content, and create a hybrid semantic search that combines text and vector relevance. We'll walk through key concepts like semantic versus lexical search, Elastic’s Learned Sparse EncodeR (ELSER), and how to run and compare different query types. By the end, you’ll have a working search prototype and the know-how to scale it for production.

This webinar is tailored for both novice and seasoned Elasticsearch users. It is an immersive journey into the evolving landscape of semantic search that will help you achieve excellent search results with Elasticsearch.
