Search 360°: From Query Understanding to LLM-Enhanced Retrieval - Livestream

Search systems are evolving rapidly, powered by advances in deep learning, embeddings, and now large language models. This talk offers a 360° view of modern search architectures: from query understanding and candidate generation to pre-ranking, ranking, and re-ranking. We’ll explore how hybrid retrieval (sparse + dense), multi-task learning, and LLM-assisted query understanding are redefining search quality and personalization. Attendees will gain a systems-level understanding of how each layer contributes to relevance, diversity, and user satisfaction, and where to focus next for scalable innovation.
