What Is Reranking in Vector Search? | RAG vs User Search Results

🧠 Ever wondered why your vector search results aren’t always perfectly relevant? In this short 6-minute video, I’ll explain the concept of reranking, the difference between RAG (retrieval-augmented generation) and user-facing vector search, and show you how to implement reranking using a cross-encoder model from the FastEmbed package. By the end, you’ll know exactly when and how to use reranking for better search relevance. Vector search is powerful — but in some cases, the top results from similarity search might not match the user’s intent perfectly. That’s where reranking comes in. In this video, you’ll learn: ✅ The difference between RAG vs user-facing search results ✅ Why reranking is important for user-facing vector search ✅ How to use cross-encoder models for reranking ✅ A practical FastEmbed demo of reranking search results This tutorial is perfect for anyone building AI search systems, chatbots, recommendation engines, or semantic search applications.
