While searching in the databases, it is likely that you will com across outdated and/or offensive terminology. Because most databases use a controlled vocabulary it can be very difficult for them to keep up with evolving terminology.
In this case, looking for author-supplied keywords may provide you with better search terms. Author-supplied keywords can usually be found at the beginning of an academic paper. Or by viewing the detailed record* of an article.
