The alternative operators result in equivilant expressions as the primary operator.  They were added to the filter parser to make expressions easier to read.  Primary and alternative operators may be mixed and matched within or across expressions.

 

Examples:

 

(( TypeOfCollision = TypeOfCollision.RearEnd ) | ( Type of Collision = TypeOfCollision.SideSwipe)) & (Injuries >= 1)

 

is the same as

 

(( TypeOfCollision .EQ. TypeOfCollision.RearEnd ) .OR. ( Type of Collision .EQ. TypeOfCollision.SideSwipe)) .AND. (Injuries .GTE. 1)
