You can serach for items just like you do in the eCandidus™ Dekstop, it allows you to type in a keyword or phrase and displays a list of items that match the criteria.
You can then scroll through the list and select which item to view by pressing on it.
Note that the image shown is displaying both the search string and a list of phone messages. 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.
