R. de M. aA tool for searching multiple compressed collections.h[electronic resource] c2003 aABSTRACT: In this paper, we introduce a research prototype of a system for searching for information directly through multiple compressed collections. We combine, in a single framework, four techniques for efficient, low overhead text retrieval: inverted index compression, block addressing, sequential searching in compressed text, and a mechanism for ranking the query results per collection. This single framework can reduce the storage overhead as well as search time, and can be applied to several scenarios where there is frequent access but not as many updates to textual documents, e.g., digital libraries. aInformation aBusca de informação aCompressão de textos aText compression1 aNASCIMENTO, M.
