ABSTRACT
Caching technologies have been widely employed to boost the performance of Web search engines. Motivated by the correlation between terms in query logs from a commercial search engine, we explore the idea of a caching scheme based on pairs of terms, rather than individual terms (which is the typical approach used by search engines today). We propose an inverted list caching policy, based on the Least Recently Used method, in which the co-occurring correlation between terms in the query stream is accounted for when deciding on which terms to keep in the cache. We consider not only the term co-occurrence within the same query but also the co-occurrence between separate queries. Experimental results show that the proposed approach can improve not only the cache hit ratio but also the overall throughput of the system when compared to existing list caching algorithms.

Re-ranking search results using query logs
CIKM '06: Proceedings of the 15th ACM international conference on Information and knowledge managementThis work addresses two common problems in search, frequently occurring with underspecified user queries: the top-ranked results for such queries may not contain documents relevant to the user's search intent, and fresh and relevant pages may not get ...
Adaptive time-to-live strategies for query result caching in web search engines
ECIR'12: Proceedings of the 34th European conference on Advances in Information RetrievalAn important research problem that has recently started to receive attention is the freshness issue in search engine result caches. In the current techniques in literature, the cached search result pages are associated with a fixed time-to-live (TTL) ...
