1. Make a list of keywords related to your topic. Are there broader or narrower terms?
2. Create a search strategy using the Boolean operators, AND; OR. For example, venous thrombosis OR DVT OR deep vein thrombosis
3. To search for case reports in Fusion, this strategy works well: "case study" OR "case studies" OR "case report" OR "case reports". In PubMed, you can easily limit a search to "Case Report".
4. Remember to use the appropriate limits (e.g. peer-reviewed, date range, English language, study type, etc.) in the databases. The limits may be somewhat different, depending on what database(s) you search.
