Summer of Relevance: Tickets Available!

Did you miss Haystack? This summer, we’ll be fulfilling our mission of empowering search teams, showing you how it’s done with 100% open source tools, by holding a full week of search relevance training.

August 6th and 7th, “Think Like a Relevance Engineer

On August 6th and 7th, we’ll hold public Solr or Elasticsearch “Think Like a Relevance Engineer” Training. This training class has been an eye opener for many organizations, setting the groundwork for dramatic relevance improvements in their organizations. Engineers, data scientists, and product managers at Eventbrite, Elsevier, LexisNexis, Spotify,, and many others have upskilled their team on how to solve challenging search relevance problems. By spending a day on measurement, methodology, and product concerns and a second day on relevance tuning techniques, we bring together the technical know-how with the experimental, user-oriented hypothesis-driven mindset needed to improve relevance. Join us! We promise your brain will hurt with what you learn.

August 8th and 9th, “Hello LTR” Learning to Rank Training

On August 8th and 9th, you can continue on to our Hello LTR – Learning to Rank training. This training demystifies Learning to Rank – using Machine Learning to improve relevance ranking. Really there’s no reason for you to fear getting into Learning to Rank. We believe anyone can learn to do this, on their own. Our first class we trained a major US Newspaper publisher, a major e-commerce retailer in the US, and a major music streaming service (Spotify). We gather training data, train models, deploy them to the search engine, and analyze how to improve them with better features and training data. We learn how to incorporate clicks and conversions to generate search training data, and real-life ‘production’ concerns of using machine learning to improve relevance.
