Geocoding suggestions provide a mechanism for implementing character-by- character auto-complete. Using a text input and optional SuggestParameters, suggested addresses can be quickly found and presented to the user. Suggestions are not limited to addresses, they can also be used for POIs Points of Interest). To return a focused set of suggestions, set the SuggestParameters::preferredSearchLocation or the SuggestParameters::searchArea. Apply the suggestParameters to your search with SuggestListModel::suggestParameters.
This QML type supports the following default properties. A default property may be declared inside another declared object without being assigned explicitly to a property.
The list of categories used for suggestions.
The category parameter limits the types of places for which the service searches, thus eliminating false positive matches and potentially speeding up the search process. You can specify categories by different levels of detail. For example, if you were searching for somewhere to eat, you could specify the category as "Korean Food" for something specific, "Food" for something more generic, or even "POI" for something very generic.
Note: Categories are currently not supported with local locators. However, a gazateer-style locator could be used instead to get a similar output.

The country code used for suggestions.
Examples of country codes include
CN for China,
IS for Iceland, and
US for The United States.

[default] preferredSearchLocation : Point
The preferred search location of a suggestion.
The search operation can sort result items by their proximity to a preferred search location, such as the user's current location. The priority of the items within 50,000 meters of this location are boosted relative to items that are farther away.
For example, when searching by name for a business with many locations in the area, there will be many matched items even when a search area is specified. The user would have to look through the items to find the closest store. When the preferred search location is set to the user's current location, the locator can prioritize the items based on proximity to the user.
By default, no preferred search location is set.
[default] searchArea : Geometry
The search area of a suggestion.
For example, you may want to only search for addresses that are inside of the map view's currently visible extent.
