Using Boolean Operators
Boolean operators connect your search words together to either narrow or broaden your set of results. Using Boolean Operators will provide better and more accurate results. The three basic Boolean operators are: AND, OR, and NOT.
- AND: Retrieves articles that contain ALL terms. NARROWS down the search.
Search example: "Child Obesity" AND "California"
- OR: Retrieves articles with ANY of the terms. BROADENS the search.
Search example: Obesity OR overweight children OR juveniles
- NOT: Eliminates articles containing the SECOND term. NARROWS the search.
Search example: Depression AND teens NOT adults
