Hybrid Search Lessons Learned - Designing Systems for RAG and Conventional Search

Learn to design and implement hybrid search solutions that serve both RAG and conventional search use cases in this conference talk from Haystack EU 2025. Discover the decision-making process behind balancing hardware resources and research priorities when team capacity is limited. Explore the reusable nature of nested index structures and master the art of building effective hybrid queries while controlling latency and managing costs. Understand how to tune relevance specifically for LLM applications and navigate the practical challenges search teams face in production environments. Gain insights into successfully rolling out hybrid search technology in organizations traditionally dependent on keyword matching, including strategies for explaining the technology, creating compelling prototypes, and overcoming organizational resistance. Walk away with practical strategies, real-world examples, and knowledge of common pitfalls to avoid when bringing hybrid search into enterprise production environments.
