This is for enhanced address search. In Taiwan, a full address may contain lane (sub-branch of a road/street) number and alley (sub-branch of a lane) number. With this function, you can specify a very detailed address and it will return the exact coordinates for navigation, instead of approximated coordinates (i.e. interpolated from the two ends of a road/street).
