Tip: You will find more (and sometimes better) keywords as you search by scanning titles and abstracts of the articles you find. Adjust your search accordingly!
Tip: Add in keywords like "epidemiology", "risk factors", or "morbidity" to find information about these aspects of your public health problem
Other keywords (synonyms)
"acquired immunodeficiency syndrome"
3. Combine your keywords in a meaningful way
Use the word "OR" to combine all synonyms and use the word "AND" to narrow your search. After combining all of your keywords, your search strategy will look something like this: drug* AND (inject* OR intravenous) AND (AIDS OR "acquired immunodeficiency syndrome")
Tip: Put quotation marks around phrases
Tip: Use an asterisk at the end of a word to capture all alternate endings (for example, use inject* to find inject, injection, injecting, etc.)
