| Parameter | Description |
|---|---|
query |
The query string to match to a location on the map. |

An array of VEFindResult Class objects. For a Geocode call, this argument will always be null.
An array of VEPlace Class objects.

Remarks
The Geocode method only returns results with high match confidence to the callback function.
