Defining Terms

Boolean operators are the words that we use when connecting two or more keywords in database searches. They include: 

AND: Use AND between keywords when you want your results to include ALL keywords (e.g., "Kale AND "swiss chard" AND spinach)

OR: Use OR between keywords when you want your results to include ANY of the keywords (e.g., "blueberry OR raspberry OR blackberry")

NOT: Use NOT to exclude keyword(s) from your search (e.g., Kale NOT "swiss chard")

"   " : Use quotations around a phrase of two or more words (e.g., "swiss chard")

*     : Use the asterix to find all alternative endings of a root word, including its singular and plural endings (e.g. raspberr* will return raspberries, raspberry and raspberried)
