It can be very difficult to brainstorm keywords about a topic. Why? Usually it's because you are not an expert. You don't know how experts are talking about a topic.
Use the record for an article, when available. You will see subject terms/keywords and you can use the abstract.
I pay attention to unfamiliar terms.
I pay attention to things that are measurable. Researchers base conclusions on things they measure.
Discovering search terms in this way gives us a good chance of finding like articles.
