Keywords are important words and concepts used to find resources (books, articles, things to buy, cat memes, etc.).
Your first keywords will come from your research question.
You can get more keywords from:
Choose simple but clear keywords and connect them with boolean language (AND, OR, NOT)
|AND||Searches for places where both keywords appear together|
|OR||Searches for either of the keywords. They might be together or they might not.|
|NOT||Searches for places where the first keyword appears without the second.|
