We propose result page models with varying granularities for navigational queries and show that this approach provides a better utilization of cache space and reduces bandwidth requirements.

A five-level static cache architecture for web search engines
Ozcan, Rifat; Altıngövde, İsmail Sengör; Barla Cambazoglu, B.; Junqueira, Flavio P.; Ulusoy, Ozgur (2012-09-01)
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. In this paper, we describe a multi-level static cache architecture that stores five different item types: query results, precomputed scores, posting lists, precomputed intersections of posting lists, and documents. Moreover, we propose a greedy heuristic to prioritize items for caching, based on gains computed by us...
Advanced methods for result and score caching in web search engines
Yafay, Erman.; Altıngövde, İsmail Sengör; Department of Computer Engineering (2019)
Search engines employ caching techniques in main memory to improve system efficiency and scalability. In this thesis, we focus on improving the cache performance for web search engines where our contributions can be separated into two main parts. Firstly, we investigate the impact of the sample size for frequency statistics for most popular cache eviction strategies in the literature, and show that cache performance improves with larger samples, i.e., by storing the frequencies of all (or, most of) the quer...
Efficient processing of category-restricted queries for Web directories
Altıngövde, İsmail Sengör; Ulusoy, Oezguer (2008-01-01)
We show that a cluster-skipping inverted index (CS-IIS) is a practical and efficient file structure to support category-restricted queries for searching Web directories. The query processing strategy with CS-IIS improves CPU time efficiency without imposing any limitations on the directory size.
A Cost-Aware Strategy for Query Result Caching in Web Search Engines
Altıngövde, İsmail Sengör; Ulusoy, Oezguer (2009-01-01)
Search engines and large scale IR systems need to cache query results for efficiency and scalability purposes. In this study, we propose to explicitly incorporate the query costs in the static caching policy. To this end, a query’s cost is represented by its execution time, which involves CPU time to decompress the postings and compute the query-document similarities to obtain the final top-N answers. Simulation results using a large Web crawl data and a real query log reveal that the proposed strategy impr...
Using object-oriented materialized views to answer selection-based complex queries
Alhajj, R; Polat, Faruk (1999-09-01)
Presented in this paper is a model that utilizes existing materialized views to handle a wide range of complex selection-based queries, including linear recursive queries. Such queries are complex because it is almost impossible for naive users to predict the formulation of their predicate expressions. Object variables bound to objects in the result of a query are allowed to appear in the predicate of that query. Also, the predicate definition is extended to make it possible to have in the output only a sub...
