Whenever you identify useful articles for your research topic, such as you have mentioned, always look at the official subject headings that accompany the articles.
Then you can redo the search using appropriate subject headings. Using subject headings may pull up related articles that don't necessarily use the same keywords you initially used. It's a good way to expand your search.
