What are Boolean Operators?
Boolean operators connect your search words together to either narrow or broaden your results in a database (like PubMed) or search engine (like Google Scholar).
Boolean operators are the words "AND", "OR" and "NOT".
Identifying Theories Using Databases
Remember to check MeSH TERMS and use keywords when building your search.
Limit search results on the left-hand side of the screen. Remember to:

Remember to use SUBJECT HEADINGS to help make searching easier. Most citations in CINAHL are indexed.
Scopus uses KEYWORD SEARCHING only.
