Q. Is there a way to limit database search results to a specific quantitative or qualitative research method?

To limit your search results to quantitative research, use the term "quantitative research" or another quantitative methodology and the drop down menu as shown below to change the field to SU Subject Terms. 

Some search results may also include the "Limit By" filter for methodology on the left hand side as shown below. Select the box to limit results to quantitative studies.
