This is coming from a non-PhD, please help me out:
If I have a broad interest in a topic, and I want to assess what are the current (in the last 5 years I guess) high-impact research done in said topic, where are the places I should look, and some general tips on how to search?
Eg: say I'm interested in application of AI/ML in education, or what are the key factors impacting engagement in MOOCs, for instance. What search engines should I try, and any tips on how to search? I'm specifically asking about scientific research searching and overview, not general articles. If this can't be answered in general I can also try to provide some specific fields of interest.
