After identifying the best databases or journals for your topic, you'll want to think about the best way to approach your search. You have a number of options and each has its advantages.
Keywords
Keyword Searching is your most basic strategy and can be a great starting point (when you use Google, you are doing a keyword search). As you've probably learned, however, keyword searches will often return too many or often unrelated results.
- Choose words and short phrases over sentences.
- Brainstorm different ways to describe your topic.
- Use a thesaurus (like thesaurus.com).
- Use the limiters described in the videos here to refine your results in whatever ways seem most useful.
- Ask your classmates and friends!
Controlled Vocabulary (Subject Terms)
Controlled Vocabulary (i.e., subject terms) can be another useful tool. You can discover subject terms related to your topic by looking at an article you've already found (usually after the abstract) or by exploring the assigned list of terms (also sometimes called subject headings). Look for the subject tab located within a specific database such as Academic Search or Education Research Complete. Clicking on a subject term will take you to a list of other articles that have been tagged with the same heading. {As tagging becomes more common, you'll also find lists of keywords and related tags that will offer more options for exploring your topic. Like a hashtag search, however, subject terms are only valuable if they're used.)
