2013 Proceedings of the 36th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '13  
Web search engines cache results of frequent and/or recent queries. Result caching strategies can be evaluated using different metrics, hit rate being the most well-known.  ...  We evaluate the most wellknown static, dynamic, and hybrid result caching strategies under this new metric.  ...  CONCLUSION We proposed the financial cost as a new evaluation metric for query result caches in web search engines.  ...

2011 Lecture Notes in Computer Science  
Web search engines are known to cache the results of previously issued queries.  ...  Moreover, using a realistic cost model, we evaluate the performance of different result prefetching strategies for the proposed hybrid cache and the baseline HTML-only cache.  ...  In practice, when a request comes for a Q, i pair (the ith result page of query Q), the Web search engine proactively fetches the F successive result pages associated with the query, that is, Q, i + 1  ...

Strategies for setting time-to-live values in result caches

Fethi Burak Sazoglu, B. Barla Cambazoglu, Rifat Ozcan, Ismail Sengor Altingovde, Özgür Ulusoy
2013 Proceedings of the 22nd ACM international conference on Conference on information & knowledge management - CIKM '13  
In web query result caching, staleness of queries are often bounded via a time-to-live (TTL) mechanism, which expires the validity of cached query results at some point in time.  ...  Moreover, we propose hybrid approaches obtained by pair-wise combination of these mechanisms.  ...  INTRODUCTION Query result caching is a commonly used technique in web search engines [3] . In this technique, the results of previously processed user queries are stored in a cache.  ...

A five-level static cache architecture for web search engines

2012 Information Processing & Management  
Caching is a crucial performance component of large-scale web search engines, as it greatly helps reducing average query response times and query processing workloads on backend search clusters.  ...  Moreover, we propose a greedy heuristic to prioritize items for caching, based on gains computed by using items' past access frequencies, estimated computational costs, and storage overheads.  ...  Conclusion In this work, we have presented a hybrid static cache architecture that brought together different types of caches that are independently managed in web search engines.  ...
