쿼리 자동완성

쿼리 자동완성 서비스는 입력 시 추천 쿼리를 반환하여 텍스트 기반 지역 검색을 위한 쿼리 예측을 제공하는 데 사용할 수 있습니다.

쿼리 Autocomplete 요청

쿼리 자동 완성 서비스는 Places API의 일부이며 Places API와 API 키 및 할당량을 공유합니다.

쿼리 자동 완성 서비스를 사용하면 실시간 지역 쿼리 예상 검색어를 애플리케이션에 추가할 수 있습니다. 특정 위치를 검색하는 대신 사용자가 '뉴욕시 근처의 피자'와 같은 카테고리 검색을 입력할 수 있습니다. 그러면 서비스에서 문자열과 일치하는 추천 쿼리 목록으로 응답합니다. 쿼리 자동완성 서비스는 전체 단어 및 하위 문자열을 모두 일치시킬 수 있으므로 사용자가 입력할 때 애플리케이션에서 쿼리를 전송하여 즉시 예상 검색어를 제공할 수 있습니다.

쿼리 자동완성 요청은 다음 형식을 사용하는 HTTP URL입니다.

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

여기서 output은 json 또는 xml일 수 있습니다.

쿼리 자동완성 요청을 시작하기 위해서는 특정 매개변수가 필요합니다. URL의 표준에 따라 모든 매개변수는 앰퍼샌드(&) 문자를 사용하여 구분합니다. 매개변수와 가능한 값 목록은 아래에 나와 있습니다.

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.

  • 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

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.

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

A textual identifier that uniquely identifies a place. To retrieve information about the place, pass this identifier in the placeId field of a Places API request. For more information about place IDs, see the Place IDs overview.

optionalstring

See place_id.

optionalArray<string>

Contains an array of types that apply to this place. For example: [ "political", "locality" ] or [ "establishment", "geocode", "beauty_salon" ]. The array can contain multiple values. Learn more about Place types.

PlaceAutocompleteMatchedSubstring

FieldRequiredTypeDescription
requirednumber

Length of the matched substring in the prediction result text.

requirednumber

Start location of the matched substring in the prediction result text.

PlaceAutocompleteStructuredFormat

FieldRequiredTypeDescription

main_text

requiredstring

Contains the main text of a prediction, usually the name of the place.

main_text_matched_substrings

required Array<PlaceAutocompleteMatchedSubstring>

Contains an array with offset value and length. These 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.

secondary_text

optionalstring
