```

## Discussion

The value of this key must be an <doc://com.apple.documentation/documentation/Foundation/NSValue> object containing a Boolean value. The value <doc://com.apple.documentation/documentation/Swift/true> indicates a case-insensitive search; <doc://com.apple.documentation/documentation/Swift/false> indicates a case-sensitive search.
