Elastic London Meetup: Rightmove & Signal Media and a new free security plugin for Elasticsearch

I finally made it to a London Elastic Meetup again after missing a few of the recent events: this time Rightmove were the hosts and the first speakers. They described how they had used Elasticsearch Percolator to run 3.5 million stored searches on new property listings as part of an overall migration from the Exalead search engine and Oracle database to a new stack bas...Continue reading

How to build a search relevance team

We've spent a lot of time working with clients who recognise that their search engine isn't delivering relevant results to users. Often this is seen as solely a technical problem, which can be resolved simply by changing query parameters or the search engine configuration - but technical teams need clear direction on why a result should or should not appear at a certain position, not just request for general relevance improvements. It's thus important to consider relevance as...Continue reading

Announcing our new book, Searching the Enterprise

For the last year or so I've been working with Professor Udo Kruschwitz of the University of Essex on a long-form journal article on enterprise search - although at 156 pages this is more of a book than a journal. Released as part of the Foundations and TrendsĀ® in Information Retrieval series by Now Publishing, the b...Continue reading

ECIR 2017 Industry Day, our book & a demo of live TV factchecking

I visited Aberdeen before Easter to speak at Industry Day, a part of the European Conference on Information Retrieval. Following a reception at Aberdeen's Town House (a wonderful building) hosted by the Lord Provost I spent an evening with various information retrieval luminaries including Professor Udo Kruschwitz of the University of Essex. We had a chance to discuss the book we're co-authoring (draft title 'Searching the Enterprise', designed as a review of t...Continue reading

London Lucene/Solr Meetup – Introducing Marple & Solr Classification

A small crowd for this month's London Lucene/Solr Meetup, kindly hosted by Barclays in their sumptuous Canary Wharf offices. I introduced the Meetup and spoke briefly on how Flax is currently looking for team members (want to work on a variety of cutting-edge open source search projects in the UK and abroad? Get in touch!) before introducing Flax's Alan Woodwar...Continue reading

Recipe for a strategic search review

We're sometimes asked by clients to examine not just their technical implementation of search, but also the wider picture: how search functionality is exposed to users, how it compares to competitors' websites and best practice. This process usually takes us ten days to two weeks and results in a highly detailed report with clear recommendations for improvement. This process is slightly different each time, but usually includes the following steps, shown with some examples of questions we mig...Continue reading

A fabulous FactHack for Full Fact

Last week we ran a hackday for Full Fact, hosted by Facebook in their London office. We had planned to gather a room full of search experts from our London Lucene/Solr Meetup and around twenty people attended from a range of companies including Bloomberg, Alfresc...Continue reading

Just the facts with Solr & Luwak

It won't have escaped your notice that factchecking is very much in the news recently due to last year's political upheavals in both the US and UK and the suspected influence of fake news on voters. Both traditional and social media organisations are making efforts in this area; examples include Channel 4 and Faceboo...Continue reading
