# SKIndexCopyDocumentIDArrayForTermID(_:_:)

Obtains document IDs for documents that contain a given term.

## Declaration

```swift
func SKIndexCopyDocumentIDArrayForTermID(_ inIndex: SKIndex!, _ inTermID: CFIndex) -> Unmanaged<CFArray>!
```

## Parameters

- `inIndex`: The index to search.
- `inTermID`: The ID of the term to search for.

## Return Value

Return Value An array of CFNumbers, each the ID for a document URL object that points to a document containing the search term.

## Discussion

Discussion SKIndexCopyDocumentIDArrayForTermID searches a single index for documents that contain a given term. The search uses a term ID, not a term string. To get the ID of a term, use SKIndexGetTermIDForTermString(_:_:). Term IDs are index-specific; that is, a term has a different ID in each index in which it appears. If you want to search for all the documents containing a term in a set of indexes, call this function in turn for each index, using the index-specific term ID in each case.
