The user taps the search icon (in the toolbar) to transform it into a focused search bar.

• As a user types, historical search suggestions can be shown beneath the search bar.
• Upon entering a query or choosing a suggestion, pressing 'Return' submits the search.
• When displaying results, the search text field remains visible, but not in focus.
• Tapping the 'Up arrow' releases the focus from search, dismisses suggestions, and the on-screen keyboard, and returns the toolbar to its original state.
