Those of us who have been working in the search sector for a while know that search tuning isn’t just a matter of installing the default configuration, pointing the engine at some content and starting it up – in fact, if you do just that you’ll probably end up with a search user experience that’s even worse then whatever you’re replacing and certainly a lot worse than your competitors’ solution. It’s also no longer about just knowing how one engine behaves and the magic tweaks to improve it – you need to understand the fundamentals of search and how a range of different products and projects implement this. You also need to understand user requirements and their often entirely subjective views of what is a ‘good’ and ‘bad’ search result, plus how different types of businesses can use search technology for site search, enterprise search, media monitoring, process improvement and myriad of other uses.

Over the last year or so we’ve seen the emergence of a new profession dedicated to improving how search systems present information to users – Relevance Engineering. Importantly this covers not just the technical aspects of search, but the business aspects – understanding the why as much as the how. Relevance engineers understand that search tuning is a multifaceted problem and there are no magic bullets (or magic AI robots) that will do all the work for you. I’ve started to write about relevance engineering recently to try and define what it means.

One of my favourite events last year was the first Haystack conference run by our partners Open Source Connections, which brought together both experienced relevance engineers and those new to the profession. It was friendly, informal, focused and informative. In fact, I enjoyed it so much that by the second day I was already thinking about how to bring the event to Europe – which we did successfully in October.

I’m very happy to say that Haystack is back in April 2019 and the Call for Papers is open until January 9th. If you’ve got an exciting relevance project or idea to talk about please do submit it. See you there!

It’s been a couple of weeks now since the first Haystack search relevance conference in Europe, which we ran with our partners Open Source Connections (OSC). Just under a hundred people came to the Friends’ House in Euston for a day of talks covering both the business and technical aspects of relevance engineering. Doug Turnbull of OSC started the day by introducing what would be a major theme of the conference, Learning to Rank, and how Bloomberg had used and benefited from open sourcing their LTR plugin for Solr. Karen Renshaw of Zoro (a division of Grainger Global Online) talked about how to tune relevance from a business perspective. Sebastian Russ of Tudock showed how even something as simple as an Excel spreadsheet can be a useful visualisation tool for relevance, while Alessandro Benedetti and Andrea Gazzarini of Sease demonstrated Rated Ranking Evaluator, a complete platform for relevance measurement. After lunch, Torsten Köster & Fabian Klenk of Shopping 24 and consultant René Kriegler described their journey with LTR for an ecommerce site and Agnes Van Belle of Textkernel showed how similar techniques can be applied to recruitment search. Tony Russell-Rose was our last speaker on strategies and tools for managing complex Boolean queries.

My only regret was how little time I had personally to catch up with the attendees, many of whom were from Flax clients past and present – I must have had 20 or 30 very brief chats during the day! Luckily a few of us went on for a drink afterwards and eventually a curry nearby. It was a very long day but from the feedback we’ve recieved so far a very successful one. We hope to make this a regular event on the calendar.

Thanks to all who made the event possible, our speakers and everyone who came – the slides are now available on the event website.
