Haystack EU 2025 Call for Papers is open now! CFP closing date is 24 July, 2025.
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!
