2021/12/06 - Amazon Location Service - 1 new6 updated api methods
Changes This release adds support for Accuracy position filtering, position metadata and autocomplete for addresses and points of interest based on partial or misspelled free-form text.
Generates suggestions for addresses and points of interest based on partial or misspelled free-form text. This operation is also known as autocomplete, autosuggest, or fuzzy matching.
Optional parameters let you narrow your search results by bounding box or country, or bias your search toward a specific position on the globe.

list
An optional parameter that indicates a preference for place suggestions that are closer to a specified position.
If provided, this parameter must contain a pair of numbers. The first number represents the X coordinate, or longitude; the second number represents the Y coordinate, or latitude.
For example, [-123.1174, 49.2847] represents the position with longitude -123.1174 and latitude 49.2847.
(float) --
list
An optional parameter that limits the search results by returning only suggestions within a specified bounding box.
If provided, this parameter must contain a total of four consecutive numbers in two pairs. The first pair of numbers represents the X and Y coordinates (longitude and latitude, respectively) of the southwest corner of the bounding box; the second pair of numbers represents the X and Y coordinates (longitude and latitude, respectively) of the northeast corner of the bounding box.
For example, [-12.7935, -37.4835, -12.0684, -36.9542] represents a bounding box where the southwest corner has longitude -12.7935 and latitude -37.4835, and the northeast corner has longitude -12.0684 and latitude -36.9542.
(float) --
list
An optional parameter that limits the search results by returning only suggestions within the provided list of countries.
Use the ISO 3166 3-digit country code. For example, Australia uses three upper-case characters: AUS.
(string) --
string
[REQUIRED]
The name of the place index resource you want to use for the search.
string
The preferred language used to return results. The value must be a valid BCP 47 language tag, for example, en for English.
This setting affects the languages used in the results. It does not change which results are returned. If the language is not specified, or not supported for a particular result, the partner automatically chooses a language for the result.
Used only when the partner selected is Here.
integer
An optional parameter. The maximum number of results returned per request.
The default: 5
string
[REQUIRED]
The free-form partial text to use to generate place suggestions. For example, eiffel tow.

{'DevicePositionUpdates': {'Accuracy': {'Horizontal': 'double'},
'PositionProperties': {'string': 'string'}}}
Evaluates device positions against the geofence geometries from a given geofence collection.
This operation always returns an empty response because geofences are asynchronously evaluated. The evaluation determines if the device has entered or exited a geofenced area, and then publishes one of the following events to Amazon EventBridge:
ENTER if Amazon Location determines that the tracked device has entered a geofenced area.
EXIT if Amazon Location determines that the tracked device has exited a geofenced area.
