Autosuggest

What is autosuggest?

Autosuggest, also known as autocomplete, is the process of using incomplete text to search for place names and addresses. For example, you can search for "New Y", "Dodgers S", and "Cali" to get a list of suggested place names that match.

You can use autosuggest to build applications that:

• Autocomplete addresses and places as you type.
• Provide a list of suggestions for incomplete address and place names.
• Refine place names and addresses to improve geocoding accuracy.

How autosuggest works

You can get address and place name suggestions by making an HTTP request to the geocoding service suggest operation or by using client APIs. Specify the address or place name text, and optionally, additional parameters to refine the search.

You can provide text for a partial place name or a partial address to get search results. Typically 2-3 characters are needed to start searching.

To refine the search and improve accuracy, you can provide additional information such as the location, search extent, category, and country code.

The geocoding service parses the text and uses all of the parameters provided to return a set of suggestions. Each suggestion contains text (address or place name), isCollection (single distinct place or multiple with the same name or category), and magicKey (search identifier) properties.
