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.

Get in touch!) before introducing Flax's Alan Woodwar...Continue reading

A fabulous FactHack for Full Fact

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

Meetup at Big Data London – One-click Solr & Factchecking with Solr

Not one, but three Lucene hackdays coming soon!

So I'm thus very happy to announce we'll be involved in three Lucene hackday events over the next two months: Firstly, Continue reading

Boosts Considered Harmful – adventures with badly configured search

During a recent client visit we encountered a common problem in search - over-application of 'boosts', which can be used to weight the influence of matches in one particular field. For example, you might sensibly use this to make results that match a query on their title field come higher in search results. However in this case we saw huge boost values used (numbers in the hundreds) which were probably swamping everything else - and it wasn't at all clear where the values had come from, be it ex...Continue reading

Setting up your first Quepid test case

Quepid is an innovative tool from our partners Open Source Connections, which allows you to bridge the gap between content owners (who really know what's in your search index and how people might search for it) and search developers (who can tweak the search engine to improve relevance, given some examples of 'good' and 'bad' results for a query). We're increasingly using it in...Continue reading
