Knowing the difference between search fields helps you dig deeper into a database to find relevant information.
Keyword: searches anywhere and everywhere for the search term. You get lots of results but fewer will be relevant to your research.
Subject: searches only in the subject headings for the term. You will get results where your search term has been described as one of the main subjects of an item, meaning fewer results but much more relevant sources of information.
