Abstract: Literature search is a commonly used strategy or a method of collecting evidence on a given research question, specifically for a Clinical Evaluation Report. A precise literature search not only provides accurate evidence but also saves time and efforts during collation of such data. However, unless implemented correctly, literature search can be misleading, time-consuming, or useless. Focusing the literature search on a precise topic and obtaining relevant evidence in a stipulated time requires high skill levels. Despite several guidance documents and papers, the process of literature search has various types of errors.
