When you are starting your research with a broad topic (for example, diabetes) it is important to
focus your research in some way. Here are several ideas:
- Focus on a particular aspect of a condition/disease (Drug therapies for diabetes)
- Focus on a particular population (Diabetes in African-American males)
- Focus on a particular location (Prevalence and treatment of diabetes in Asia)
- Focus on a particular time period (Treatment of diabetes during the 19th century)
If you don't narrow down your search in some way, you will retrieve way too many results.
