Two Boolean operators that are important in finding information are AND and OR. The AND is used to connect two different concepts and the OR is used between concepts that are synonymous. It is critical to put parentheses around a search expression that contains an OR. Here is an example:
The first part of this statement will find material about children or adolescents, teens or juveniles. The second part will look for the words "policy" or "policies". The AND then links the first set with the second. This should be an effective way to look for polices dealing with children's issues.
