When using the databases to locate articles, keep the following tips in mind:
Be sure to break your topic into relevant keywords instead of simply typing it into the search box. If your search returns a much bigger or smaller number of results than you anticipated, try revising your keywords.
You can use Boolean operators to broaden or narrow your search results. To find results about cats and dogs, use the search cats AND dogs. To find results about cats, but not dogs, use the search cats NOT dogs. To find results where either cats or dogs are mentioned, use the search cats OR dogs.
Spelling counts. Databases have keyword searching, but unlike Google, they won't correct your spelling for you.
