What we’re about
We’re a group of search & AI enthusiasts committed to sharing knowledge, tips & tricks, cool tools and techniques. We’ll cover a wide range of search technologies, from OpenSearch to Solr, Weaviate to Vespa - and our talks will be informative and useful, not just product pitches. The rise of AI has changed the world of search - so we want to know how it might solve some of our oldest problems, from data quality to query understanding to conversational interfaces. We’d love to hear about how you used search & AI to solve real business problems, create entirely new ways to access information and supercharge your business. Topics covered at our events will include how to measure & evaluate search & AI applications, indexing techniques, search engine operations, relevance tuning, site search, enterprise search, e-commerce search, scaling, RAG & other generative AI but also old-school search … anything cool, anything interesting, anything Search!

November Meetup at Tesco
Tesco, The Lever Building, 85 Clerkenwell Road, EC1R 5AR, London, GBWe're hosted this time by Tesco. The event will start at 6.30pm and finish by 9pm, with food and drinks available. This will be an in-person event (but we will try to record the talks and share the videos later).
Our first talk will come from our hosts Tesco by Max Grogan (Data Scientist) and George Sykes (Senior Data Science Engineer): Judgement Day: Rethinking Search Evaluation with Language Models
"Relevance labels are the backbone of evaluating search performance, yet human labelling is slow, costly, and hard to scale. This talk explores how LLMs can act as automated judges, producing scalable, human-like labels for ecommerce search. We’ll examine our learnings from trying to build such a system including building reliable evaluation datasets as well as the trade-offs of adopting different model and system architectures.".The second talk will come from Bharav Patel (Specialist Solution Architect , OpenSearch, AWS):
Query understanding with LLM : Approaches and Optimization in OpenSearch.
"Ever wondered how to make your OpenSearch smarter with LLMs? This session dives into how Large Language Models are revolutionizing search and making it way more intuitive for users.
We'll walk through the AI-powered search lifecycle and show you how LLMs can supercharge different parts of your search system:- Query Understanding: Help your search actually "get" what users are looking for, even when they don't phrase things perfectly
- Query Rewriting: Smart techniques to rephrase and expand queries so you catch more relevant results
- Result Reranking: Use ML models to bubble up the best results to the top (because nobody likes digging through page 2)
- Context-Aware Search: Make search feel personalized by understanding user context and preferences
Learn practical tips and real optimization strategies for implementing these LLM features in OpenSearch, whether you're building a new search experience from scratch or improving an existing one to make it smarter and more user-friendly."
We'll also make time for Q&A on all things search and AI and some general networking. Our Search Meetup is organised by The Search Juggler, OpenSearch and Eliatra.
