Space efficient caching of query results in search engines
TL;DR: The proposed model is envisioned to improve the cache hit rate and system throughput as it allows storing more query results within a particular cache space, in return to a negligible increase in the cost of preparing the final query result page.
Proceedings ArticleDOI
Efficient processing of category-restricted queries for web directories
TL;DR: It is shown that a cluster-skipping inverted index (CS-IIS) is a practical and efficient file structure to support category-restricted queries for searching Web directories and improves CPU time efficiency without imposing any limitations on the directory size.
