See conference video - http://www.lucidimagination.com/devzone/events/conferences/revolution/2011 Earlier this year, Sensis launched its Business Search API, which allows publishers to develop local search propositions powered by the two million business listings contained in the Australian Yellow Pages® and White Pages® directories. This case study will explore Sensis’ strategic direction for search and explain how the framework and metrics by which search is managed at Sensis were used to define our search roadmap. Key architectural decisions including our use of Solr and MongoDB will be discussed as well as our approach to real-time search tuning and quality management.
