A vector search can retrieve candidates quickly, but the nearest vectors are not always the passages that best answer the user&rsquo;s question.</p> <p><strong>Reranking</strong> adds a second relevance step. The system first retrieves a reasonably broad candidate set with a fast method, then applies a more precise model to reorder those candidates before selecting context for the LLM.</p>
