Boolean operators
AND, OR, NOT
Boolean operators are the logical connectives AND, OR, and NOT, used to combine or modify conditions in searches, programming, and formal logic.
AND narrows results by requiring all conditions: cats AND dogs finds only items mentioning both.
OR broadens by accepting any condition.
NOT excludes: jaguar NOT car.
Named for mathematician George Boole, these operators form the basis of digital logic and database queries.
