Online result cache invalidation for real-time web search

Xiao Bai, Flavio P. Junqueira
2012 Proceedings of the 35th international ACM SIGIR conference on Research and development in information retrieval - SIGIR '12  
Caches of results are critical components of modern Web search engines, since they enable lower response time to frequent queries and reduce the load to the search engine backend.  ...  For enhancing invalidation efficiency, the generation time of cached queries and their chronological order with respect to the latest index update are used to early prune unaffected queries.  ...  Once a search engine returns results for a query, we process the same query against the main search index to obtain the ground truth (its ideal set of results).  ...

Modeling Static Caching in Web Search Engines [chapter]

Ricardo Baeza-Yates, Simon Jonassen
2012 Lecture Notes in Computer Science  
In this paper we model a two-level cache of a Web search engine, such that given memory resources, we find the optimal split fraction to allocate for each cache, results and index.  ...  The final result is very simple and implies to compute just five parameters that depend on the input data and the performance of the search engine.  ...  For designing an efficient caching architecture for web search engines there are many trade-offs to consider.  ...

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.  ...  Query processing overview Web search engines are composed of multiple replicas of large search clusters.  ...

Compact Snippet Caching for Flash-based Search Engines

Rui Zhang, Pengyu Sun, Jiancong Tong, Rebecca Jean Stones, Gang Wang, Xiaoguang Liu
2015 Proceedings of the 38th International ACM SIGIR Conference on Research and Development in Information Retrieval - SIGIR '15  
With the trend of using flash-based solid state drives (SSDs) instead of hard disk drives for search engine storage, the bottleneck of snippet generation shifts from I/O to computation.  ...  In response to a user query, search engines return the topk relevant results, each of which contains a small piece of text, called a snippet, extracted from the corresponding document.  ...  INTRODUCTION Caching is an important method for reducing query latency in search engines.  ...

A refreshing perspective of search engine caching

Berkant Barla Cambazoglu, Flavio P. Junqueira, Vassilis Plachouras, Scott Banachowski, Baoqiu Cui, Swee Lim, Bill Bridge
2010 Proceedings of the 19th international conference on World wide web - WWW '10  
Commercial Web search engines have to process user queries over huge Web indexes under tight latency constraints.  ...  In this work, we first argue that the real problem in today's caching for large-scale search engines is not eviction policies, but the ability to cope with changes to the index, i.e., cache freshness.  ...  SYSTEM MODEL Search engines execute essentially three main tasks: crawling, indexing, and query processing.  ...
