McMaster Libraries (2:42)
Not all authors use the same language to describe similar topics, so you will need to try a variety of searches in databases.
Identify the key concepts of your topic.
Next, create a list of synonyms or related words for each concept. Think of words that would actually appear in a book or article.
Stick to using 2-4 keywords at a time when searching.
Example: What are the interpretations of paleolithic art?
interpretations --> criticism, history, meaning, etc.
