 When you search for a full or partial address using Azure Maps Search Service, it takes your search term and returns the longitude and latitude coordinates of the address. This process is called geocoding. The ability to geocode in a country is dependent upon the road data coverage and the geocoding precision of the geocoding service.

+   Azure Maps [Fuzzy Search API](https://docs.microsoft.com/rest/api/maps/search/getsearchfuzzy) is recommended service to use when you do not know what your user inputs are for a search query. The API combines Point of Interest (POI) search and geocoding into a canonical 'single-line search'. 
 
    1. The `minFuzzyLevel` and `maxFuzzyLevel`, help return relevant matches even when query parameters do not exactly correspond to the desired information. Most search queries default to `minFuzzyLevel=1` and `maxFuzzyLevel=2` to gain performance and reduce unusual results. Take an example of a search term "restrant", it is matched to "restaurant" when the `maxFuzzyLevel` is set to be 2. The default fuzzy levels can be overridden as per request needs.

        * `Addr` - **Address Ranges**: For some streets, there are address points that are interpolated from the beginning and end of the street; those points are represented as address ranges.
        * `Geo` - **Geographies**: Areas on a map that represent administrative division of a land, that is, country, state, city.

When multiple brands are provided, only results that belong to (at least) one of the provided list will be returned.
