Boolean Searching allows you to combine key words/key concepts by using three “operators”.
These operators are:
Using AND to combine two or more search terms will NARROW the search by retrieving only those records that contain all of the terms combined.
CHILDREN AND TELEVISION
Using OR increases the number of records retrieved. If you combine two or more search terms with OR the computer will retrieve all the records containing any of the search terms. OR is generally used to group synonymous terms or variations of spelling.
The OR operator is used to BROADEN a search.
TV OR TELEVISION
TEENAGER OR ADOLESCENT
BEHAVIOR OR BEHAVIOUR
Using NOT, NARROWs your search by eliminating records that contain a search term you do not want in your search
