Layanan Query Autocomplete dapat digunakan untuk memberikan prediksi kueri untuk penelusuran geografis berbasis teks, dengan menampilkan saran kueri saat .
Permintaan Query Autocomplete
Layanan Query Autocomplete adalah bagian dari Places API dan membagikan kunci API dan kuota dengan Places API.
Layanan Query Autocomplete memungkinkan Anda menambahkan lokasi geografis dengan cepat terhadap aplikasi Anda. Daripada mencari lokasi, pengguna dapat mengetikkan penelusuran kategori, seperti "pizza di dekat New York" dan layanan akan merespons dengan daftar kueri yang disarankan yang cocok dengan {i>string<i}. Karena layanan Query Autocomplete bisa cocok dengan kedua kolom kata dan {i>substring<i}, aplikasi bisa mengirim kueri saat pengguna mengetik memberikan prediksi dengan cepat.
Permintaan Query Autocomplete adalah URL HTTP dengan bentuk berikut:
https://maps.googleapis.com/maps/api/place/queryautocomplete/output?parameters
dengan output
dapat berupa json
atau
xml
.
Diperlukan parameter tertentu untuk memulai permintaan Query Autocomplete.
Sesuai dengan standar dalam URL, semua parameter dipisah menggunakan tanda ampersan
(&
) karakter. Daftar parameter dan kemungkinannya
disebutkan di bawah ini.
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 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
Defines a point, as
latitude,longitude
coordinates, around which to search. The Places service uses the location to bias the search to prefer to show results in the area defined bylocation
andradius
; results outside of the defined area may still be displayed.Thelocation
parameter may be overridden 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.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
.

Jika layanan Places menampilkan hasil JSON dari penelusuran, layanan tersebut akan menempatkannya
dalam array predictions
. Meskipun layanan tersebut kembali
tidak ada hasil (misalnya jika location
dilakukan dari jarak jauh),
masih menampilkan array predictions
yang kosong. Respons XML terdiri
dari nol atau beberapa elemen <prediction>
.
