ABSTRACT: This research is aimed at studying the relationship between perceived usefulness and satisfaction with query reformulation tools in Science Direct Data Base. A descriptive analytic method was used to study the relationship between variables; the data were collected using a researcher-made questionnaire. The samples were selected from among Students of Information Science in Islamic Azad University of Research and Science Center of Khuzestan who had the seminarCourse (n = 28). The findings showed that users main reason for query reformulation was not having enough time to investigate all retrieved results (Mean = 4.66). They also showed that based on perceived satisfaction and perceived usefulness, users used the query tools which bounded them to the topic (Mean = 3.92 for usefulness and M =3.83 for satisfaction). In addition, Pearson’s correlation co-efficiency (r = 0.939) at (0.000) significance level showed that users perceived usefulness from query reformulation tools increased satisfaction.
