RAM and dynamic pruning schemes to reduce query evaluation times. While only a small portion of lists are processed with dynamic pruning, current systems still store the entire inverted list in cache. In this paper we investigate caching only the pieces of the inverted lists that are actually used to answer a query during dynamic pruning. We examine an LRU cache model, and two recently proposed models. We also introduce a new dynamic pruning scheme for impact-ordered inverted lists. Using two large web collections and corresponding query logs we show that, using an LRU cache, our new pruning scheme reduces the number of disk accesses during query processing time by 7%-15% over the state-of-the-art impact-ordered baseline, without reducing answer quality. Surprisingly, however, we discover that using our new pruning scheme makes little difference to disk traffic when the more sophisticated caching schemes are employed.
