Boolean Redux: Performance of Advanced versus Simple Boolean Searches and Implications for Upper-Level Instruction

Abstract

Building off an earlier study, which examined whether or not it was beneficial to teach Boolean logic to introductory students, the present study examines the efficacy of Boolean OR searching in more advanced search strategies, for example, capstone projects and graduate theses and dissertations. Results show that both simple and advanced Boolean searches yield relevant results. Based on relevance, there is no compelling evidence that either search is superior. To capture all the literature on a topic, however, it is important that upper-level students know the relevant databases for their discipline and perform multiple searches. Results can help inform whether teaching Boolean search skills to upper-division students in disciplinary contexts is time well spent.
