One of the more commonly practiced advanced search strategies is Boolean searching using operators like "AND" and "OR".
- Use "AND" between search terms to retrieve fewer results (i.e., narrow down your search) and find only articles that include all of the terms specified.
- Use "OR" to retrieve more results (i.e., broaden your search results) and find articles that include any of the terms specified. In the latter case, using synonyms or similar words separated by the word "OR" may also help expand your search.
