Remarks

This stateless API provides automatic suggestions for natural language queries for the data sources in the provided project and location.

The service provides a resourceless operation suggestQueries that can be called to get a list of suggestions for a given incomplete query and scope (or list of scopes) under which the query is to be interpreted.

There are two types of suggestions, ENTITY for single entity suggestions and TEMPLATE for full sentences. By default, both types are returned.

Example Request:

GetSuggestions({
parent: "locations/us/projects/my-project"
scopes:
"//bigquery.googleapis.com/projects/my-project/datasets/my-dataset/tables/my-table"
query: "top it"
})

The service will retrieve information based on the given scope(s) and give suggestions based on that (e.g. "top item" for "top it" if "item" is a known dimension for the provided scope).

Methods

Create()

public static AutoSuggestionServiceClient Create()

Synchronously creates a AutoSuggestionServiceClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use AutoSuggestionServiceClientBuilder.

Returns
Type	Description
AutoSuggestionServiceClient	The created AutoSuggestionServiceClient.

CreateAsync(CancellationToken)

public static Task<AutoSuggestionServiceClient> CreateAsync(CancellationToken cancellationToken = default)

Asynchronously creates a AutoSuggestionServiceClient using the default credentials, endpoint and settings. To specify custom credentials or other settings, use AutoSuggestionServiceClientBuilder.

Parameter
Name	Description
cancellationToken	CancellationToken The CancellationToken to use while creating the client.

Returns
Type	Description
TaskAutoSuggestionServiceClient	The task representing the created AutoSuggestionServiceClient.

ShutdownDefaultChannelsAsync()

public static Task ShutdownDefaultChannelsAsync()

Shuts down any channels automatically created by Create() and CreateAsync(CancellationToken). Channels which weren't automatically created are not affected.

Returns
Type	Description
Task	A task representing the asynchronous shutdown operation.

Remarks

After calling this method, further calls to Create() and CreateAsync(CancellationToken) will create new channels, which could in turn be shut down by another call to this method.

SuggestQueries(SuggestQueriesRequest, CallSettings)

public virtual SuggestQueriesResponse SuggestQueries(SuggestQueriesRequest request, CallSettings callSettings = null)

Gets a list of suggestions based on a prefix string. AutoSuggestion tolerance should be less than 1 second.

Parameters
Name	Description
request	SuggestQueriesRequest The request object containing all of the parameters for the API call.

AutoSuggestionServiceClient autoSuggestionServiceClient = AutoSuggestionServiceClient.Create();
// Initialize request argument(s)
SuggestQueriesRequest request = new SuggestQueriesRequest
{
    ParentAsLocationName = LocationName.FromProjectLocation("[PROJECT]", "[LOCATION]"),
    Scopes = { "", },
    Query = "",
    SuggestionTypes =
    {
        SuggestionType.Unspecified,
    },
};
// Make the request
SuggestQueriesResponse response = autoSuggestionServiceClient.SuggestQueries(request);

SuggestQueriesAsync(SuggestQueriesRequest, CallSettings)

public virtual Task<SuggestQueriesResponse> SuggestQueriesAsync(SuggestQueriesRequest request, CallSettings callSettings = null)

Gets a list of suggestions based on a prefix string. AutoSuggestion tolerance should be less than 1 second.

Parameters
Name	Description

    Scopes = { "", },
    Query = "",
    SuggestionTypes =
    {
        SuggestionType.Unspecified,
    },
};
// Make the request
