We host and attend events on search & relevance across the world. Come and join our Search Meetup groups or meet us as we talk at a conference! You can see the next events we'll attend below.

We run Haystack, the search relevance conference, twice a year as a large event in the USA and Europe plus we tour smaller Haystack events in Europe and the USA. We also host the London Lucene/Solr Meetup and the Haystack LIVE! Meetup (which presents regular online talks on search & relevance). We’re also regular speakers at other events including ApacheCon, Berlin Buzzwords, MICES (Mix Camp for E-commerce), Search Solutions, Taxonomy Bootcamp & Enterprise Search Summit. Come and meet our team!

Why you should come to one of our events

You’ll learn why search is still so hard to get right, how to measure search quality and collaborate effectively to improve it. You’ll hear from others facing the same problems as you, understand how to implement cutting-edge AI-powered techniques while getting the very best from your current technology.

Our events our peer-to-peer, friendly and approachable – not just vendors pitching their products, but real people telling you what works and importantly what doesn’t!

Talks from past events are available on our Youtube channel.
