Boolean is a set of commands that can be used in almost every search engine, database, or online catalogue. The most popular Boolean commands are AND, OR, and NOT. Other commands include parentheses, truncation, and phrases.
Please see U of T's FAQs on Boolean Operators for additional information.
Using Boolean command NOT in your search tells the search engine to give you results that contain the word(s) you entered except the word following NOT.
Psychology NOT Developmental: any results that contain the word "psychology" will appear in your results list except those results that also contain the word "developmental".
