Search has come a long way. From exact matching and Boolean queries to semantic search, embeddings, RAG and agentic AI.

Join the London Java Community and Redis for a practical journey through the evolution of search and retrieval, led by Sam Agbede.

In this session, Sam will explore how each generation of search has tackled a different challenge, from traditional information retrieval through to the AI-powered systems we're building today.

We'll look at:

  • How exact matching and Boolean search shaped information retrieval
  • How TF-IDF and BM25 rank results across large document collections
  • How embeddings and semantic search can find meaning beyond exact keywords
  • How Retrieval-Augmented Generation (RAG) uses retrieved context to support more grounded AI responses
  • How AI agents combine search, memory, tools and verification
  • How Redis 8 and Redis Search support full-text, vector and hybrid search for real-time applications
  • Practical examples of retrieval and verification in mathematical research and agentic AI systems

Whether you're working with Java, building search applications, exploring RAG, or simply interested in how retrieval is evolving alongside AI, this session will give you a practical understanding of the technologies and ideas shaping modern search.

Sam Agbede is a technology professional with a focus on Java, AI and modern application development. Through his work and community involvement, Sam is passionate about exploring practical ways developers can use emerging technologies to build better real-world systems.

We hope you'll join us!

A huge thank you to Redis

We'd also like to say a huge thank you to our friends at Redis for their continued support of the London Java Community throughout 2026.

Redis has been a fantastic partner to the LJC this year, supporting our events and helping us continue to create valuable opportunities for our community to learn, connect and share knowledge.

We're incredibly grateful for their ongoing support and look forward to continuing to work together to bring more great technical content to the Java community.
