The report describes the effects that a controlled vocabulary has on the indexing and searching operations of the document retrieval system established by the University of Dayton for the Air Force Materials Laboratory. The system contains about 30,000 scientific and technical reports covering all aspects of materials research and is controlled by a vocabulary of 10,000 terms. In general, the use of a controlled vocabulary has been found to be very beneficial to the overall operation of the system. Also described are three search strategies that are used to effectively retrieve information in a format that is more useful to a user than merely a list of document numbers.
