Google Scholar uses ranking algorithms to find the most relevant academic research possible. However, its algorithms use an exact keyword match that excludes synonymous search terms that may be overlooked or neglected by researchers. This paper aims to improve on the current Google Scholar Search System by allowing a broad topic search algorithm to diversify and allow synonymous search terms to be included and ranked with other results. The authors propose a Design Science method to improve the Google Scholar Search System by developing a broad topic prototype that will add synonymous keywords into Google Scholar ranking algorithms. The results from twenty users will be evaluated by means of Mean Reciprocal Rank and Discounted Cumulative Gain. This improvement will introduce a modern approach to academic search engines systems, and to allow researchers who overlook potential search queries, an improved core topic diversity, quality, and discoverability of published research.
