Abstract : Experience of browsing with a text retrieval system is reported. The technique discussed consists of adding and deleting query terms on successive iterative cycles. The number of hits consistently increased, while the number of false drops consistently decreased on successive cycles. The search system used allows non-Boolean free form query statements. Therefore, an abstract may be used as a query with the objective of finding similar abstracts from the file. (Author)
