Query Autocomplete

Mit dem Dienst „Query Autocomplete“ können Sie eine Abfragevorhersage für textbasierte geografische Suchanfragen erstellen. Dabei werden während der Eingabe vorgeschlagene Abfragen zurückgegeben.

Query Autocomplete-Anfragen

Der Dienst „Query Autocomplete“ ist Teil der Places API und nutzt denselben API-Schlüssel und dasselbe Kontingent wie die Places API.

Mit dem Dienst „Query Autocomplete“ können Sie Ihrer Anwendung spontan geografische Abfragevorhersagen hinzufügen. Statt nach einem bestimmten Standort zu suchen, kann der Nutzer eine kategoriebezogene Suche eingeben, z. B. „Pizza in der Nähe von Berlin“. Der Dienst antwortet dann mit einer Liste von Vorschlägen für Suchanfragen, die mit dem String übereinstimmen. Da der Query Autocomplete-Dienst sowohl vollständige Wörter als auch Teilstrings abgleichen kann, können Anwendungen Abfragen senden, während der Nutzer tippt, um spontan Vorhersagen zu liefern.

Eine Anforderung mit Query Autocomplete ist eine HTTP URL der folgenden Form:

https://maps.googleapis.com/maps/api/place/queryautocomplete/output?parameters

Dabei kann output entweder json oder xml sein.

Es sind bestimmte Parameter für die Initiierung einer Query Autocomplete-Anforderung erforderlich. Wie bei URLs üblich, werden alle Parameter durch kaufmännische Und-Zeichen (&) getrennt. Die Liste der Parameter und ihrer möglichen Werte sind unten aufgeführt.

Required parameters

  • input

    The text string on which to search. The Place Autocomplete service will return candidate matches based on this string and order results based on their perceived relevance.

Optional parameters

  • language

    The language in which to return results.

    • See the list of supported languages. Google often updates the supported languages, so this list may not be exhaustive.
    • If language is not supplied, the API attempts to use the preferred language as specified in the Accept-Language header.
    • The API does its best to provide a street address that is readable for both the user and locals. To achieve that goal, it returns street addresses in the local language, transliterated to a script readable by the user if necessary, observing the preferred language. All other addresses are returned in the preferred language. Address components are all returned in the same language, which is chosen from the first component.
    • If a name is not available in the preferred language, the API uses the closest match.
    • The preferred language has a small influence on the set of results that the API chooses to return, and the order in which they are returned. The geocoder interprets abbreviations differently depending on language, such as the abbreviations for street types, or synonyms that may be valid in one language but not in another. For example, utca and tér are synonyms for street in Hungarian.
  • location

    The point around which to retrieve place information. This must be specified as latitude,longitude.

    The location parameter may be overriden if the query contains an explicit location such as Market in Barcelona. Using quotes around the query may also influence the weight given to the location and radius.
  • offset

    The position, in the input term, of the last character that the service uses to match predictions. For example, if the input is Google and the offset is 3, the service will match on Goo. The string determined by the offset is matched against the first word in the input term only. For example, if the input term is Google abc and the offset is 3, the service will attempt to match against Goo abc. If no offset is supplied, the service will use the whole term. The offset should generally be set to the position of the text caret.

  • radius

    Defines the distance (in meters) within which to return place results. You may bias results to a specified circle by passing a location and a radius parameter. Doing so instructs the Places service to prefer showing results within that circle; results outside of the defined area may still be displayed.

    The radius will automatically be clamped to a maximum value depending on the type of search and other parameters.

    • Autocomplete: 50,000 meters
    • Nearby Search:
      • with keyword or name: 50,000 meters
      • without keyword or name
        • Up to 50,000 meters, adjusted dynamically based on area density, independent of rankby parameter.
        • When using rankby=distance, the radius parameter will not be accepted, and will result in an INVALID_REQUEST.
    • Query Autocomplete: 50,000 meters
    • Text Search: 50,000 meters

Wenn der Places-Dienst JSON-Ergebnisse für eine Suche zurückgibt, werden diese in einem predictions-Array platziert. Auch wenn der Dienst keine Ergebnisse zurückgibt (z. B. bei einem Remote-location), wird ein leeres predictions-Array zurückgegeben. XML-Antworten bestehen aus null oder mehr <prediction>-Elementen.

PlacesQueryAutocompleteResponse

FieldRequiredTypeDescription
required Array<PlaceAutocompletePrediction>

Contains an array of predictions.

See PlaceAutocompletePrediction for more information.

requiredPlacesAutocompleteStatus

Contains the status of the request, and may contain debugging information to help you track down why the request failed.

See PlacesAutocompleteStatus for more information.

optionalstring

When the service returns a status code other than OK, there may be an additional error_message field within the response object. This field contains more detailed information about thereasons behind the given status code. This field is not always returned, and its content is subject to change.

optionalArray<string>

When the service returns additional information about the request specification, there may be an additional info_messages field within the response object. This field is only returned for successful requests. It may not always be returned, and its content is subject to change.

PlacesAutocompleteStatus

Status codes returned by service.

  • OK indicating the API request was successful.
  • ZERO_RESULTS indicating that the search was successful but returned no results. This may occur if the search was passed a bounds in a remote location.
  • INVALID_REQUEST indicating the API request was malformed, generally due to the missing input parameter.
  • OVER_QUERY_LIMIT indicating any of the following:
    • You have exceeded the QPS limits.
    • Billing has not been enabled on your account.
    • The monthly $200 credit, or a self-imposed usage cap, has been exceeded.
    • The provided method of payment is no longer valid (for example, a credit card has expired).
    See the Maps FAQ for more information about how to resolve this error.
  • REQUEST_DENIED indicating that your request was denied, generally because:
    • The request is missing an API key.
    • The key parameter is invalid.
  • UNKNOWN_ERROR indicating an unknown error.

PlaceAutocompletePrediction

FieldRequiredTypeDescription
requiredstring

Contains the human-readable name for the returned result. For establishment results, this is usually the business name. This content is meant to be read as-is. Do not programmatically parse the formatted address.

required Array<PlaceAutocompleteMatchedSubstring>

A list of substrings that describe the location of the entered term in the prediction result text, so that the term can be highlighted if desired.

See PlaceAutocompleteMatchedSubstring for more information.

requiredPlaceAutocompleteStructuredFormat

Provides pre-formatted text that can be shown in your autocomplete results. This content is meant to be read as-is. Do not programmatically parse the formatted address.

See PlaceAutocompleteStructuredFormat for more information.

required Array<PlaceAutocompleteTerm>

Contains an array of terms identifying each section of the returned description (a section of the description is generally terminated with a comma). Each entry in the array has a value field, containing the text of the term, and an offset field, defining the start position of this term in the description, measured in Unicode characters.

See PlaceAutocompleteTerm for more information.

optionalinteger

The straight-line distance in meters from the origin. This field is only returned for requests made with an origin.

optionalstring
