More examples of each term and search strategy are given below. A few tips to start:
cognitive behavioral therapy becomes (cognitive AND behavioral AND therapy)
Use AND to connect two or more concepts
classroom management AND student behavior
Some databases use "+" instead of (or in addition to) AND.
Use OR to connect two or more similar concepts (synonyms)
assessments OR evaluations
Use NOT to exclude concepts from your search.
osteoporosis NOT arthritis
Some databases use "-" or AND NOT instead of NOT.
Here are a number of examples in combining three concepts with Boolean terms.
In addition to Boolean terms, search strategies can include other options including Proximity Indicators (e.g., NEAR, ADJ, and PRE), truncation or Wildcard symbols (?, and *), the hyphen (-), and specialized options (e.g. SAME or EXACT). See the Additional Search Options tab for more details on using these search strategies.
