1. AND: write 'and' between different words to focus your search
Example: Search SARS and globalization and you'll only find articles with all of these terms.
2. OR: write 'or' between synonyms to expand your search
Example: (SARS or "severe acute respitory syndrome") will find articles with either of these terms. It's important to include synonyms to ensure you find all articles relevant to your topic. For example, if you typed SARS but the article said severe acute respiratory syndrome, you would miss it if you didn't include the full name of the disease as a synonym.
3. Truncation *: Use truncation * to expand your search
Example: Globaliz* will find globalize, globalizing, and globalization.
