# string

Allows the client to specify a single string for searching.

## Declaration

```swift
optional var string: String { get }
```

## Discussion

Discussion If the client cannot logically or efficiently flatten itself into a single string, then the string(at:effectiveRange:endsWithSearchBoundary:) and stringLength() methods should be implemented instead.
