In this book, we aim to provide a fairly comprehensive overview of the scalability and efficiency challenges in large-scale web search engines. More specifically, we cover the issues involved in the design of three separate systems that are commonly available in every web-scale search engine: web crawling, indexing, and query processing systems. We present the performance challenges encountered in these systems and review a wide range of design alternatives employed as solution to these challenges, specifically focusing on algorithmic and architectural optimizations. We discuss the available optimizations at different computational granularities, ranging from a single computer node to a collection of data centers. We provide some hints to both the practitioners and theoreticians involved in the field about the way large-scale web search engines operate and the adopted design choices. Moreover, we survey the efficiency literature, providing pointers to a large number of relatively important research papers. Finally, we discuss some open research problems in the context of search engine efficiency.

About the Author

B. Barla Cambazoglu received his B.S., M.S., and Ph.D. degrees, all in computer engineering, from the Computer Engineering Department of Bilkent University in 1997, 2000, and 2006, respectively. After getting his Ph.D. degree, he worked as a postdoctoral researcher in Bilkent University for a short period of time. In 2006, he joined the Biomedical Informatics Department of the Ohio State University as a postdoctoral researcher. In 2008, he joined Yahoo Labs as a postdoctoral researcher. He received research scientist and senior research scientist positions at the same institution, in 2010 and 2012, respectively. Between 2013 and 2015, he was a senior manager, heading the web retrieval group in Yahoo Labs Barcelona. His main research interests are distributed information retrieval and web search efficiency. In 2010, 2011, 2014, and 2015, he co-organized the LSDS-IR workshop. He was the proceedings chair for WSDM'09 and the poster and proceedings chairs for ECIR'12. He served as an area chair in SIGIR'13 and SIGIR'14. He regularly serves on the program committees of SIGIR, WWW, and KDD conferences. He has many papers published in prestigious journals including IEEE TPDS, JPDC, JASIST, Inf. Syst., ACM TWEB, and IP&M, as well as papers and tutorials presented at top-tier conferences, such as SIGIR, CIKM, WSDM, WWW, and KDD.
