Step One: List the keywords from your research topic.
Example: cancer, treatment, medicine, cure, prevention
Step Two: Select the words that you think are the most important. In doing this, think about the words that are essential in
explaining your topic. Example: cancer, treatment
Step Three: Combine these keywords and AND. This instructs the computer that both words must occur.
Step Four: Now use more of your original keywords, introducing them into the equation one by one. Use OR to separate them,
and enclose the OR statement in parentheses. Example: cancer and (treatment or cure)
Spend some time playing with this technique; it can produce some excellent results.
