In general, it is best to think in terms of concepts or keywords
when searching online resources. Most electronic databases do not
answer direct questions. Even those databases that do allow natural
language searching usually produce better results with keyword
searching. Make your search more precise and productive by using
Boolean logic (AND, OR, NOT). The following examples will
illustrate the use of these Boolean operators.
Problem: Student is looking for articles that will answer this question - How does violence on TV affect children?
Solution: Choose the important terms from the question and use the
AND operator between each term to locate articles that include all the important terms.
Possible Search Statement: television AND violence AND children
Problem: Student is looking for information on laptops. In addition to getting articles about laptops the student is also
getting unwanted articles about desktop computers.
Solution: Eliminate the unwanted articles by using the NOT operator
Possible Search Statement: laptops NOT desktops
Problem: Student is trying to find more information about AIDS.
Solution: Expand the search using the OR operator.
Possible Search Statement: AIDS OR HIV.
