Reference documentation and code samples for the Google Cloud Retail V2 Client class CompletionServiceClient.
Service Description: Autocomplete service for retail.
This feature is only available for users who have Retail Search enabled. Enable Retail Search on Cloud Console before using this feature.
This class provides the ability to make remote calls to the backing service through method calls that map to API methods.
Many parameters require resource names to be formatted in a particular way. To assist with these names, this class includes a format method for each type of name, and additionally a parseName method to extract the individual identifiers contained within formatted names that are returned by the API.

__construct
Constructor.
Parameters | |
---|---|
Name | Description |
options |
array
Optional. Options for configuring the service API wrapper. |
↳ apiEndpoint |
string
The address of the API remote host. May optionally include the port, formatted as "
|
↳ credentials |
string|array|FetchAuthTokenInterface|CredentialsWrapper
The credentials to be used by the client to authorize API calls. This option accepts either a path to a credentials file, or a decoded credentials file as a PHP array. Advanced usage: In addition, this option can also accept a pre-constructed Google\Auth\FetchAuthTokenInterface object or Google\ApiCore\CredentialsWrapper object. Note that when one of these objects are provided, any settings in $credentialsConfig will be ignored. |
↳ credentialsConfig |
array
Options used to configure credentials, including auth token caching, for the client. For a full list of supporting configuration options, see Google\ApiCore\CredentialsWrapper::build() . |
↳ disableRetries |
bool
Determines whether or not retries defined by the client configuration should be disabled. Defaults to |
↳ clientConfig |
string|array
Client method configuration, including retry settings. This option can be either a path to a JSON file, or a PHP array containing the decoded JSON data. By default this settings points to the default client config file, which is provided in the resources folder. |
↳ transport |
string|TransportInterface
The transport used for executing network requests. May be either the string |
↳ transportConfig |
array
Configuration options that will be used to construct the transport. Options for each supported transport type should be passed in a key for that transport. For example: $transportConfig = [ 'grpc' => [...], 'rest' => [...], ]; See the Google\ApiCore\Transport\GrpcTransport::build() and Google\ApiCore\Transport\RestTransport::build() methods for the supported options. |
↳ clientCertSource |
callable
A callable which returns the client cert as a string. This can be used to provide a certificate and private key to the transport layer for mTLS. |
completeQuery
Completes the specified prefix with keyword suggestions.
This feature is only available for users who have Retail Search enabled. Enable Retail Search on Cloud Console before using this feature.
The async variant is Google\Cloud\Retail\V2\Client\CompletionServiceClient::completeQueryAsync() .

importCompletionData
Bulk import of processed completion dataset.
Request processing is asynchronous. Partial updating is not supported.
The operation is successfully finished only after the imported suggestions are indexed successfully and ready for serving. The process takes hours.
This feature is only available for users who have Retail Search enabled. Enable Retail Search on Cloud Console before using this feature.
The async variant is Google\Cloud\Retail\V2\Client\CompletionServiceClient::importCompletionDataAsync() .
