Search relevance is a hard problem. Satisfying the user information needs across a multitude of different factors and business requirements may seem daunting, but do not despair! This Search Relevance Training teaches you how to design, develop, and configure your open source search engine to maximize how well the search results fit the user information need. Join us as we explore the milestones of search relevance to the deep internals of Apache Lucene and Elasticsearch.
Exercises and war stories from real-world problems and solutions are included.
