This report describes the work done at The University of Melbourne for the TREC- 2006 Terabyte Track. For this track, we participated in all three main tasks. We continued our work with impact-based ranking and sought to reduce indexing as well as query time. However, to support the named-page task, more conventional retrieval mechanisms were also employed. The results show that, in general, the efficiency performance is slightly better than the previous year. The effectiveness level remains the same.
