Abstract
In the first article of this three-part series, three factors were identified as major influences on the effectiveness of document retrieval, where document retrieval is concerned with the access to intellectual content. These factors are, search exhaustivity, determinacy of representation and document collection size. In this article, some of the implications of these factors for document searching are discussed, and a two-part searching procedure based on identifiable partitions is proposed.
