“Search is among the most disruptive innovations of our time. It influences what we buy and where we go. It shapes how we learn and what we believe. This provocative and inspiring book explores design patterns that apply across the categories of web, e-commerce, enterprise, desktop, mobile, social, and real time search and discovery. Using colorful illustrations and examples, the authors bring modern information retrieval to life, covering such diverse topics as relevance ranking, faceted navigation, multi-touch, and mixed reality. Search Patterns challenges us to invent the future of discovery while serving as a practical guide to help us make search applications better today.” (Peter Morville & Jeffery Callender)
