Solr consulting support

We’ve been providing expert Solr consulting for over 15 years. We’ve helped organizations across the world implement powerful, scalable and accurate search engines based on these open source platforms.

Our CEO is a Solr Committer and co-authored the first book on Solr, Apache Solr Enterprise Search Server, now in its third edition.

Relevance engineering with Solr

We create and maintain open source plugins, extensions and tools for Solr including Quepid, the test-driven relevancy dashboard and a number of modules available on solr.cool and our Github.

We teach the craft of Solr relevance engineering through our Solr training, regular blogs and via our Youtube channel. We run the London Lucene/Solr Meetup and our Haystack conference series which focuses on relevance engineering. Our free Relevance Slack community has around 5000 members and a dedicated #solr channel.

Our Solr consulting experts know how to get the best out of this powerful technology – and via our Proven Process we can empower your team to deliver the value your business requires.

Apache Solr, based on Apache Lucene and available under the open source Apache license, powers search for some of the world’s largest organisations including Bloomberg, Best Buy, Sears, Instagram and AOL. Solr is highly scalable, resilient and accurate.

“Solr/Lucene knowledge expanded and greatly improved the abilities of our public job search. They delivered technical excellence at every turn: demonstrating expertise in Lucene internals, relevance models, and data science backed by a solid methodology for improving search relevance. OSC marries technical excellence with strategic insight: we highly recommend their experts to any search team.”
