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

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,...
