Abstract / Description:This paper evaluates the potential impact of explicit phrases on retrieval
quality through a case study with the TREC Terabyte benchmark. It compares the
performance of user- and system-identified phrases with a standard score and a
proximity-aware score, and shows that an optimal choice of phrases, including
term permutations, can significantly improve query performance.
