As many others have noted, Google have recently announced their Google Search Appliance (GSA) will not be available for sale from 2017. Search gurus Miles Kehoe and Martin White have written an insightful analysis of the move with some recommendations as to what to do - because your GSA will simply stop working once the 2-year license expires. I don't agree with Lauren...Continue reading
In my last blog post, I demonstrated how to set up and configure Solr to use the new XJoin search components we've developed for the BioSolr project, using an example from an e-commerce setting. This time, I'll show...Continue reading
As part of our work on the BioSolr project, I have been continuing to work on the various Elasticsearch ontology annotation plugins (note that even though the project started with a focus on Solr - thus the name - we have also been developing some features for Ela...Continue reading
In this blog post I want to introduce you to a new Apache Solr plugin component called XJoin. I'll show how we can use this to solve a common problem in e-commerce - how to use price discount data, provided by an external web API, to either filter the results of a product search or boost scores. A further post will show another example, using click-through data to influence the score of subsequent searches.
I had been planning not to continue with these posts, but after Matt Weber pointed out the github pull requests (which to my embarrassment I'd not even noticed) he'd made to address some methodological flaws, another attempt was the least I could do. For Solr there was a slight reduction in mean search time, from 39ms (for my original, suboptimal query structure) to 34ms and median search time from 27ms to 25ms - see figure 1. Elasticsearch, on the ...Continue reading
It's been a very busy few months for events - so busy that it's quite a relief to be back in the office! Back in late November I travelled to Vienna to speak at the FIBEP World Media Intelligence Congress with our client Infomedia about how we've helped them to migrate their media monitoring platform from the elderly, unsupported and hard to scale Continue reading
