That search bar on your website isn't just a text box anymore—it's a complex AI system with sliders for typo tolerance, vector density, and attribute weighting. In this episode, we break down the three layers of modern search: fuzzy matching for typos, semantic search for intent, and reranking for relevance. Learn when to use each layer, the common traps small teams fall into (like cranking typo tolerance too high), and why the best approach is a hybrid pipeline that combines old-school keyword matching with new-school AI. Whether you're tuning Algolia for a 50-product inventory or a 5,000-page documentation wiki, this guide cuts through the jargon to give you practical rules for making search actually work.
