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 output
은 json
또는 xml
일 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 aradius
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
orname
: 50,000 meters -
without
keyword
orname
-
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 anINVALID_REQUEST
.
-
Up to 50,000 meters, adjusted dynamically based on area density,
independent of
- with
- 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 theAccept-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
.Thelocation
parameter may be overriden if thequery
contains an explicit location such asMarket in Barcelona
. Using quotes around the query may also influence the weight given to thelocation
andradius
.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 onGoo
. The string determined by the offset is matched against the first word in the input term only. For example, if the input term isGoogle abc
and the offset is 3, the service will attempt to match againstGoo 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.
