Abstract. Shared-nothing, parallel text retrieval systems require an in-
verted index, representing a document collection, to be partitioned among
a number of processors. In general, the index can be partitioned based on
either the terms or documents in the collection, and the way the partition-
ing is done greatly affects the query processing performance of the parallel
system. In this work, we investigate the effect of these two index partition-
