Viewing Option Combination - Expressions

Boolean logic

( BodyColor = RED )	Selects all red cars.
( BodyColor = RED _ and WheelColor = GREEN )	Selects only red cars that have green wheels.
( BodyColor = RED _ or WheelColor = GREEN )	Selects all cars which are painted red plus all cars that have green wheels (so 'or' means and/or).

Nested statements

The following two statements have the same operators, but a different nesting structure:

• BodyColor = RED and ( SeatColor = GREEN or WheelColor = BLUE)
• (BodyColor = RED and SeatColor = GREEN ) or WheelColor = BLUE

A yellow car with blue wheels fits expression 2 but not expression 1.
