Reranking Is The Secret S

The one trick that makes every RAG system 40% better...

Your vector search returns 20 chunks. Some are great, some are noise. A reranker is a second model that scores each chunk specifically for your query. It's more accurate than embedding similarity because it sees the query and document together. Use Cohere Rerank or BGE Reranker. Retrieve 20 chunks with vector search, rerank them, keep the top 5. This single step improves answer quality by 30 to 40 percent. Don't skip it.
