This is the first year that Juru, a Java IR system developed over the past few years at the IBM Research Lab in Haifa, participated in TREC’s Web track. Our experiments focused on the ad-hoc tasks. The main goal of our experiments was to validate a novel pruning method, first presented at [1], that significantly reduces the size of the index with very little influence on the system’s precision. By reducing the index size, it becomes
