Boolean Search
Note: Use of all caps for Boolean operators is intentional in the examples below and is required for a search to work as intended.- A search term can be a single word like sleep or a phrase like circadian rhythm.
- This search uses OR as the default Boolean operator, so a search for circadian rhythm will return any works containing the term circadian or the term rhythm.
- A search for circadian AND rhythm will return only works that contain both terms.
- Adding quotation marks around a phrase, as in "circadian rhythm," will return only works containing that exact multi-word phrase.
- Adding NOT before a term, as in circadian NOT rhythm will return only works that contain circadian but not rhythm.
- Putting terms inside parentheses allows for more complex searches like (circadian OR rhythm) AND sleep NOT dream.
