Torus: PostgreSQL Search in Ecto - Dima Mikielewicz | Code BEAM Lite STO 2025

This talk was recorded at Code BEAM Stockholm in June 2025. If you’re curious about our upcoming event, check https://codebeamstockholm.com

Abstract
Search is a fundamental part of many applications, but choosing the right approach can be challenging. This talk explores different search strategies - from full-text and similarity searches to semantic and hybrid techniques. I’ll share insights from implementing these in a large-scale codebase serving millions of users, focusing on performance, relevance, and maintainability. Finally, I’ll introduce Torus, a library designed to integrate these search methods seamlessly into Ecto, making it easier to build and refine personalized search experiences within Elixir applications.
