Search Using Subject Terms
On the search results page, after entering your search terms, look to the limiters on the left side of the page. Find the Subject limiter and expand it. Look through the list and see if any subject terms aid in limiting your search and/or helping you discover new keywords.
If you select a subject term, the database will limit your search to the articles listed under that subject heading only.
Proquest and Ebsco Databases both use “subject” as a limiter.
