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.
