Thesaurus oriented documents retrieval system (THEODORES) is developed. The THEODORES accepts different thesauri which represent various aspects of subjects, and the performance of retrieval depens significantly upon the quality of the thesaurus. Modifications of the thesaurus are possible through a conversation with the data base. Exploration of a model structure of the subject is also possible by the effective use of the thesaurus. A logical connector and a pertinent data structure are designed to represent the Boolean operators and the thesaurus respectively. The THEODORES is possible to interpret an arbitrary query which is expressed by a combination of key words and the Boolean operators including NOT function. It is found that the efficiency of retrieval depends on the order of sequence of key words as well as on the length of key words of an input query.
