Commercial web search engines adopt parallel and replicated architecture in order to
support high query throughput. In this paper, we investigate the effect of caching on the …

This paper proposes a cache hierarchy that enables Web search engines to efficiently
process user queries. The different caches in the hierarchy are used to store pieces of data …

This paper discusses the design and implementation of an efficient caching system aimed to
exploit the locality present in the queries submitted to a Web search engine. Previous works …

Commercial Web search engines have to process user queries over huge Web indexes
under tight latency constraints. In practice, to achieve low latency, large result caches are …

We study the caching of query result pages in Web search engines. Popular search engines
receive millions of queries per day, and efficient policies for caching query results may …

In this paper we study the performance of a distributed search engine from a data caching
point of view. We compare and combine two different approaches to achieve better hit …

Large scale search engines have to cope with increasing volume of web content and
increasing number of query requests each day. Caching of query results is one of the crucial …

Large web search engines have to answer thousands of queries per second with interactive
response times. Due to the sizes of the data sets involved, often in the range of multiple …

Web search engines serve millions of query requests per day. Caching query results is one
of the most crucial mechanisms to cope with such a demanding load. In this paper, we …

This paper discusses the design and implementation of SDC, a new caching strategy aimed
to efficiently exploit the locality present in the stream of queries submitted to a Web Search …
