There is no hope of doing a perfect search (Griffiths, 1998, p97), do you agree? Before attempting to answer this question, it is important to review the definition and meaning of research. According to scholar Cresswell, “research is a step-by-step process used to gather and analyze information to increase our understanding of a topic or problem” (3). The Cambridge Online Dictionary defines research as “a detailed study of a subject, especially with a view to discovering (new) information or achieving (new) understanding”. Based on a theoretical framework, the research can be quantitative or qualitative. It is undeniable that research has become essential to produce knowledge in numerous fields such as science, technology, design, psychology, education and so on. Since the purpose of research is the advancement of human knowledge, the refinement of research has been a topic of discussion among professionals. From my point of view, I agree that perfect research does not exist. As the name suggests, research means investigating a topic again to probe and reach a new understanding. From this point, it could be argued that if perfect research exists, there will be no doubt and there will be no need to carry out further studies on the topic or area covered by perfect research. In this sense, perfection would be a lock that prevents any possibility of further examination and scrutiny. Adding new understanding to the existing knowledge bank would be impossible. Perfection is a state of being complete and correct in every way, without any flaws. Research, whether quantitative or qualitative, is a human activity that always involves some error or defect.
