Most academic research uses quantitative research methods, which deal in numbers, logic, and an objective stance, so you shouldn't have any difficulty finding them. Quantitative research methods are Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research.
To search for articles using a qualitative research method, combine your search keywords with a qualitative research method used commonly in your field of study. The qualitative research methods are phenomenological, ethnographic, grounded theory, historical, case study, and action research.
