Information Retrieval: Searching in the 21st Century

“I would recommend Information Retrieval to readers who already have a base of knowledge on core IR concepts."  (Inf Retrieval, 9 December 2010)

"The authors have definitely met the challenge of providing a comprehensive volume of factual knowledge on IR fundamentals. I highly recommend the book to those in both academia and industry." (Computing Reviews, 9 May 2011)
