Set Intersection Operators

The set intersection operators (INTERSECT and ~INTERSECT) compare two sets. Sets are strings of elements separated by the caret character. The resulting set is a string that contains only those elements present in both sets. The INTERSECT operator is case-sensitive. The ~INTERSECT operator is not case-sensitive.

Important! The sequence of elements in the resulting set is not predictable. When the operation is not case-sensitive, the case of elements in the resulting set is also not predictable.

Examples:

'BLUE JAY^ORIOLE^WREN' INTERSECT 'BLUE JAY^wren'
Result = 'BLUE JAY'

'BLUE JAY^ORIOLE^WREN' ~INTERSECT 'BLUE JAY^wren'
Result = 'BLUE JAY^WREN'
