Also known as Boolean operators, connectors are used in keyword searches to link together two or more terms.
The most commonly used connectors are AND and OR.
|AND narrows a search; you get fewer records, because both concepts must be present in the records found--here the area is in yellow. Use AND to combine different concepts in one search.||
|OR broadens a search; you get more records because OR includes each of the concepts separately, as well as both concepts when found together. OR is often used to link together related concepts.||
|NOT is often used in conjunction with AND to exclude unwanted results.||
