- Abstract
- Reports on a research project to evaluate and compare Boolean searching and methods of query reformulation using ranked output retrieval. Illustrates the design and operating features of the ranked output system, called ROSE (Ranked Output Search Engine), by means of typical results obtained by searching a database of 1239 records on the subject of cystic fibrosis. Concludes that further work is needed to determine the best reformulation tactics needed to harness the professional searcher's intelligence with that much more limited intelligence provided by the search software

- Abstract
- An experimental ranked output prototype offers the searcher choices of match method, plus some field bias and term bias options. The objective is an effective interactive alternative to Boolean systems. Presents the features of the system, together with a selection of the laboratory ebaluation test results
