The search bar is used to locate objects within a large collection of items. It is usually used in a list report pattern or list picker to allow the user to quickly navigate to an object.

When the user taps on the search bar, it shifts up and takes the place of the navigation bar, which is automatically hidden. Once the user inputs a value into the search field, results are populated within the content area.

The search bar has two variations:
A prominent search bar remains visible at all times below the navigation bar. It is used when the search is the primary action in the current screen.
A minimal search bar is hidden by default and is revealed when the user pulls down on the content area. Use a minimal search bar when search is a secondary action.
