This operator can be used to match on any one of multiple words. For example, "genomics OR genetics" will find all courses that have "genomics" in the title, or that have "genetics" in the title, or both.

This operator can be used to match on every word. For example, "genomics AND advanced" will find all courses whose title contains both the words "genomics" and "advanced". Courses that have "genomics" in the title but not "advanced", will not be matched.

Precedence

The AND operator has a higher precedence than the OR operator. This means it is evaluated first. So with this text "genomics AND advanced OR genetics", matching courses will need to have both "genomics" and "advanced" in the title, or have "genetics" in the title.

• AFNS 585 - Advanced Quantitative Genomics Matches because the title has both "Advanced" and "Genomics"
• AUBIO 260 - Principles of Genetics Matches because the title has "Genetics"
• BOT 464 - Plant Functional Genomics Does not match because, while it does have "Genomics", it doesn't have "advanced"

This operator can be used to negate the word following it. For example, "NOT genomics" will find all courses whose title does not contain the word "genomics"

Precedence

The NOT operator has the highest precedence - it will be evaluated before AND and OR. So with this text "NOT genomics AND advanced", matching courses cannot have "genomics" in the title, and must have "advanced"
