Evidence-Based Practice / Unit 3 EBP 0348 short lesson, about 20 seconds
Boolean Connectors
Captions available
The idea
Boolean connectors join search terms. AND requires both terms to appear; OR requires either one.
In practice
Two terms returning 173 and far more separately, and 62 once joined with AND.
Where people slip
The connectors are not interchangeable and not intuitive under pressure. OR gives more; AND gives less.
