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.
