The Quick Find function behaves like it's eCandidus™ Dekstop counterpart, it allows you to type in a name or other keyword and displays a list of cases (work product) that match the criteria.
You can then scroll through the list and select which case (work product) to view.
Note that the image shown is displaying both the search string and a list of cases. Normally the search string is cleared out when the search starts, when you press the Search button. This gives you visual feedback that the search took place.
