Can I search for street, suburb and city names?

Yes - the Addressfinder database contains "locations" (streets, suburbs, cities and regions) as well as addresses and these can also be searched and collected via the javascript widget.

The widget is automatically configured to have this feature disabled but it can be enabled by including the option {show_locations: true} in your javascript code. See code example.

You may also want to disable the searching of addresses from this field and this can be completed by including the option {show_addresses: false} in your javascript code. See code example.
