Most databases allow the use of AND, OR and NOT to broaden or narrow and search.
Truncation: You can use an * at the end of a word stem to broaden your search to include related terms. For example, to search for child, children or childhood use the search term child*
Putting quotes "" around words allows you to search for a phrase. For example, searching language development, without quotes, finds records with both the word 'language' and 'development' somewhere in the record. Searching "language development", with quotes, only find records with the phrase "language development".
Example: What are the psychological and mental health impacts of COVID-19?
NOTE: When you begin doing advanced searching in a new database, look for the Help or Information sections to determine how that database works, and how it may differ from other databases with which you are familiar.
