Search Engine Efficiency has been an active field of Information Retrieval research for many years and the literature is vast. When implementing a search engine it is necessary to wade through this literature and to make engineering decisions on what to implement and what to not. Andrew has recently implemented an new efficient search engine and in this presentation will outline its design. This search engine is fast and accurate, but as he will show; academically accurate. Unfortunately, it’s not quite so obvious what academic accuracy means for a user.<\/p>\n\n\n\n
