Boolean Operators

• Many databases allow use of Boolean operators in advanced searches

• Boolean operators

• AND (example: wireless AND LAN AND Wi-Fi)
• OR    (example: Java or C++)
• NOT (example: Java NOT coffee)

• Some databases require operators to be in upper case; read the Help to find out

• Some databases allow mixed operators, for example:

• Wireless and LAN not Wi-Fi
• ((A or B) and C) and not D
