Books & Resources

We wrote the book on search. 

Good search understands a user’s intent, not just what they type. While at OSC, Doug Turnbull wrote the book on search, Relevant Search, to help teams build smarter Elasticsearch and Solr applications. Our co-founder Eric Pugh helped write the very first book on Solr and our team contribute to the annual Search Insights reports from the Search Network.

“One of the best and most engaging technical books I’ve ever read.”

Trey Grainger

“Will help you solve real-world search relevance problems for Lucene-based search engines.”

Pioneers in machine learning. 

We built Elasticsearch Learning to Rank, which powers search at Yelp, Wikipedia, Snag and others. 

Since deploying learning to rank, we’ve seen a net 32% increase in conversion metrics across our historically lowest performing use-cases.

Jason Kowalewski,
Sr Director of Engineering at Snag

We built the tools. 

We also built Quepid, a search testing platform that takes the guesswork out of search relevancy. 

“Do not attempt a search project without it.”

John Bickerstaff
