If your topic is unfamiliar to you or if you are finding too little information, you may want to broaden your search. To broaden a topic, look for more general or less specific terms.
Example:
Topic: Young, Asian-American mothers
If you are finding too much information or if your information is too general, you may want to narrow your search. To narrow a topic, select terms that are more specific or descriptive.
Example:
Topic: Global Warming
Water Crisis
Windmills
Thesis: How successful are windmills in Africa?
