Is there a difference between keywords and subject terms? Yes. Keywords are the words you come up with to describe your topic. Subject terms or headings are "controlled language" words used by databases to ensure that all items relevant to a particular topic will be found.
Searching with subject headings is the most precise way to search many databases. However, it's not as flexible as a keyword search because you must know the exact term to use. It often helpful to start with your keywords and look at a few items from your results list. If you find a few good articles, look at the list of subject terms in those records. Use these terms and run your search again. Sometimes you can click on a subject term and it will automatically run the search for you.
