Think about the different themes and concepts related to your topic, then use the appropriate discipline-specific database to find related articles.
Prefer to start broad, use an interdisciplinary database:
AND link words by AND to search for all words in the same resource
OR link words by OR to search for one word or another (instead of both/all words)
NOT to eliminate results with a certain term
“Quotations” – add quotations to a group of two or more words to search for the exact phrase
