# SpotlightSearchTool.SearchReply.StageToken

An opaque type you use to identify a single pipeline stage within the Spotlight search tool.

## Declaration

```swift
struct StageToken
```

## Overview

Overview Within a single call to the Spotlight search tool’s call(arguments:) method, the tool can run one or more pipeline stages to deliver the requested results. Each stage corresponds to a specific task needed to generate the results. For example, one stage might rank the search results based on their relevance. When delivering results to your app, the tool includes a StageToken value in the SpotlightSearchTool.SearchReply structure it delivers. You can use the token to associate that data with a particular processing stage of the tool.
