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 free Search Insights reports from the Search Network, an independent group of search professionals.

“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.”
