1. Choose your search terms carefully.
2. Put them in the box and search.
3. Ignore the articles in your results list! Look for the number of results, aim for between 5 and 50.
4. Get a better list: if you have fewer than 5 results or more than 50, apply limiters and revise your search terms, then search again.
5. When you have a results list with a manageable number of relevant articles, begin to work through them by reading their articles and abstracts.
