In some cases, you may need to narrow your search to specific types of studies (phenomenology, case study, etc.) Unfortunately, most databases do not support filtering by methodology. However, I did find a workaround that gave me pretty good results in my own research. That was to direct a search term for methodology at the abstract. The abstract is very short, so authors will almost always include the type of study in that concise description. The abstract is searchable in most databases as well, which makes it a good target for our purposes.
The video below demonstrates sample searches in multiple databases.
