The "Search" widget allows a user to search for an address directly.  None of the fields on this tool are required, so any partial address (such as a street number and city name only) can be searched.  This tool ignores statuses, dates, and property categories, and only relies on the address of a property.  This means that if a property has been listed multiple times in multiple different ways (such as "For Sale" and "For Rent", or was "Withdrawn" 2 years ago, "Closed" last year, and is "Active" currently) all versions will appear.
