abstract: 
-------------------------- 
To engineer a search engine is a challenging task. Search 
engines index tens to hundreds of millions of web pages 
involving a comparable number of distinct terms. They 
answer tens of millions of queries every day. Despite the 
importance of large-scale search engines on the web, very 
little academic research has been done on them. 
Furthermore, due to rapid advance in technology and web 
proliferation, creating a web search engine today is very 
different from three years ago. This paper provides an 
in-depth description of our large-scale web search engine 
-- the first such detailed public description we know of to 
date. Apart from the problems of scaling traditional search 
techniques to data of this magnitude, there are new 
technical challenges involved with using the additional 
information present in hypertext to produce better search 
results. This paper addresses this question of how to build 
a practical large-scale system which can exploit the 
additional information present in hypertext.
