# SKIndexGetTermDocumentCount(_:_:)

Gets the number of documents containing a given term represented in an index.

## Declaration

```swift
func SKIndexGetTermDocumentCount(_ inIndex: SKIndex!, _ inTermID: CFIndex) -> CFIndex
```

## Parameters

- `inIndex`: The index containing the text of the documents you want to examine.
- `inTermID`: The terms whose occurrences you want to know.

## Return Value

Return Value A CFIndex object containing the number of documents represented in an index that contain a given term.

## Discussion

Discussion If you want to know in which documents a term appears across multiple indexes, call this function separately on each index. Before querying each index, get the index-specific term ID using SKIndexGetTermIDForTermString(_:_:). To ensure that this function takes into account document URL objects (of type SKDocument) recently added to indexes, call SKIndexFlush(_:) on each index before calling this function.
