The Search Relevance Conference!

Created and organised by OpenSource Connections

Haystack goes on tour!

Join OpenSource Connections, founders of the Haystack search relevance conference, and Paris-based search engine tech experts Adelean for an afternoon of search enlightenment - learn how to build great data-driven search experiences, find out how leading French companies run their search and look forward to the future of search powered by vectors and machine learning.

Search experts René Kriegler & Charlie Hull from OpenSource Connections and Lucian Precup and Aline Paponaud from Adelean draw on their multiple decades of experience working with some of the world’s most innovative companies to teach you how to create and tune powerful and accurate search engines. We’ll consider the core challenges of search, how to measure search quality, what tools and techniques are available and draw on many client case studies to show you how others have improved search for their users. We’ll also look at how vector search may change the game and tell you what you need to know about this growing trend.

This will be a free event, hosted by Station F, the world's biggest startup campus and sponsored by Adelean and OpenSource Connections GmbH. The event is aimed at search product owners, search relevance engineers, data scientists & machine learning engineers working on search applications. Registration is open from 9.30 am Paris time, the event will run from 10am-2pm and a light lunch will be provided.

Register for the event here. You can also join 3000 other search enthusiasts in the free Relevance Slack community to continue the discussion!


We’re also running regular Haystack LIVE Meetups featuring talks on search and relevance - and you can submit a talk here.


Haystack EU 2022 took place on September 27th this year in Berlin as a hybrid event. We enjoyed a week of search events in Berlin:

Haystack will return to the US and EU in 2023.

Haystack is the conference for improving search relevance. If you're like us, you work to understand the shiny new tools or dense academic papers out there that promise the moon. Then you puzzle how to apply those insights to your search problem, in your search stack. But the path isn't always easy, and the promised gains don't always materialize.

Haystack is the conference for organizations where search, matching, and relevance really matters to the bottom line. For search managers, developers, relevance engineers & data scientists finding ways to innovate, see past the silver bullets, and share what actually has worked well for their unique problems. Please come share and learn!
