    • Cache-based query processing for search engines 

      Cambazoglu, B. B.; Altıngovde, I. S.; Ozcan, R.; Ulusoy, Özgür (Association for Computing Machinery, 2012-11-01)
      In practice, a search engine may fail to serve a query due to various reasons such as hardware/network failures, excessive query load, lack of matching documents, or service contract limitations (e.g., the query rate limits ...
    • Cost-aware strategies for query result caching in Web search engines 

      Ozcan, R.; Altingovde, I. S.; Ulusoy, O. (Association for Computing Machinery, 2011)
      Search engines and large-scale IR systems need to cache query results for efficiency and scalability purposes. Static and dynamic caching techniques (as well as their combinations) are employed to effectively cache query ...
    • Exploiting navigational queries for result presentation and caching in Web search engines 

      Ozcan, R.; Altingovde, I. S.; Ulusoy, O. (John Wiley & Sons, Inc., 2011)
      Caching of query results is an important mechanism for efficiency and scalability of web search engines. Query results are cached and presented in terms of pages, which typically include 10 results each. In navigational ...
    • A five-level static cache architecture for web search engines 

      Ozcan, R.; Altingovde, I. S.; Cambazoglu, B. B.; Junqueira, F. P.; Ulusoy, Özgür (Elsevier Ltd, 2012)
      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 ...
    • Second chance: a hybrid approach for dynamic result caching and prefetching in search engines 

      Ozcan, R.; Altingovde, I. S.; Cambazoglu, B. B.; Ulusoy, O. (Association for Computing Machinery, 2013-12)
      Web search engines are known to cache the results of previously issued queries. The stored results typically contain the document summaries and some data that is used to construct the final search result page returned to ...
    • Static index pruning in web search engines: combining term and document popularities with query views 

      Altingovde, I. S.; Ozcan, R.; Ulusoy, O. (Association for Computing Machinery, 2012)
      Static index pruning techniques permanently remove a presumably redundant part of an inverted file, to reduce the file size and query processing time. These techniques differ in deciding which parts of an index can be ...
