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...

Mark Harwood of Elastic was first with a talk about the new Graph API and visua...

Choosing between Elasticsearch and Solr

One of the questions we're asked all the time is which of the two most popular open source search engines is best for a particular use case - and the answer is always 'it depends'. Broadly speaking, Apache Lucene/Solr and Elasticsearch are very similar in terms of features and performance. If you've already chosen one of them, there's very few reasons to incur the inevitable extra work of switching to the other. However if you're still not sure which to choose, read on. Solr,...

Better search for life sciences at the BioSolr Workshop, day 2 – Elasticsearch & others

Over the last 18 months we've been working closely with the European Bioinformatics Institute on a project to improve their use of open source search engines, funded by the BBSRC. The project was originally named BioSolr but has since grown to encompass Read more
