After you identify your research question, you can make a list of synonyms of the PICO components. This will be helpful for searching the literature.
Determine key concepts. Establish terminology so you can develop lists of key words and synonyms to use in your search. The more precise your topic is, the easier it will be to complete a literature review.
Look for keywords when reading background information or encyclopedia articles on your topic. Use a thesaurus, your textbook and subject headings in databases to find different keywords. Keep track of these words so you can use them when searching.
Determine your scope. Decide which filters/limits (e.g. demographics, language, date range, study type, geographic region) you would like to use to reduce the number of articles you need to review.
