What is the main role of keywords in structured research databases?

The primary role of keywords in structured research databases is to help researchers find relevant literature quickly. Keywords serve as essential tools in the search process, enabling users to identify studies, articles, and papers that match their specific area of interest or inquiry. By using relevant keywords, researchers can efficiently navigate the vast amount of academic literature available, narrowing down their search results to those most pertinent to their research questions.

This function significantly enhances the efficiency of the research process, allowing users to spend less time sifting through unrelated materials and more time focusing on the information that directly supports their work. In this context, keywords act as a bridge between a researcher's query and the body of existing literature, playing a crucial role in information retrieval and literature reviews.
