1. Go to your Assignment Inbox and locate the Filter and Search tools at the top right of the List pane. In the illustration below, all three filters (Open, Closed, and Archived) are set to "on."
The filters are therefore colored blue, indicating that they are selected. Since all three filters are selected, all Assignments are visible in this view.
Open Assignments are not yet begun or in progress. Closed Assignments are completed. Archived Assignments are completed and archived. The titles of Archived Assignments -- in the illustration, the Assignment at the top of the list -- are grayed out.
2. Press filters to toggle them on or off, to filter by Open, Closed, and Archived states
3. Press the Search tool in your inbox, to search within Assignments
4. Enter the text in the Search bar and press Enter.
