Instance Method Details

#complete_query(request, options = nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::CompleteQueryResponse #complete_query(data_store: nil, query: nil, query_model: nil, user_pseudo_id: nil, include_tail_suggestions: nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::CompleteQueryResponse

Completes the specified user input with keyword suggestions.

Examples:

Basic example

require "google/cloud/discovery_engine/v1"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::DiscoveryEngine::V1::CompletionService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::DiscoveryEngine::V1::CompleteQueryRequest.new

# Call the complete_query method.
result = client.complete_query request

# The returned object is of type Google::Cloud::DiscoveryEngine::V1::CompleteQueryResponse.
p result

Overloads:

  • #complete_query(request, options = nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::CompleteQueryResponse

    Pass arguments to complete_query via a request object, either of type Google::Cloud::DiscoveryEngine::V1::CompleteQueryRequest or an equivalent Hash.

    Parameters:

    • request (::Google::Cloud::DiscoveryEngine::V1::CompleteQueryRequest, ::Hash) —

      A request object representing the call parameters. Required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash.

    • options (::Gapic::CallOptions, ::Hash) (defaults to: nil) —

      Overrides the default settings for this call, e.g, timeout, retries, etc. Optional.

  • #complete_query(data_store: nil, query: nil, query_model: nil, user_pseudo_id: nil, include_tail_suggestions: nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::CompleteQueryResponse

    Pass arguments to complete_query via keyword arguments. Note that at least one keyword argument is required. To specify no parameters, or to keep all the default parameter values, pass an empty Hash as a request object (see above).

    Parameters:

    • data_store (::String) (defaults to: nil) —

      Required. The parent data store resource name for which the completion is performed, such as projects/*/locations/global/collections/default_collection/dataStores/default_data_store.

    • query (::String) (defaults to: nil) —

      Required. The typeahead input used to fetch suggestions. Maximum length is 128 characters.

    • query_model (::String) (defaults to: nil) —

      Selects data model of query suggestions for serving. Currently supported values:

      • document - Using suggestions generated from user-imported documents.
      • search-history - Using suggestions generated from the past history of SearchService.Search API calls. Do not use it when there is no traffic for Search API.
      • user-event - Using suggestions generated from user-imported search events.
      • document-completable - Using suggestions taken directly from user-imported document fields marked as completable.

      Default values:

      • document is the default model for regular dataStores.
      • search-history is the default model for [IndustryVertical.SITE_SEARCH][] dataStores.
    • user_pseudo_id (::String) (defaults to: nil) —

      A unique identifier for tracking visitors. For example, this could be implemented with an HTTP cookie, which should be able to uniquely identify a visitor on a single device. This unique identifier should not change if the visitor logs in or out of the website.

      This field should NOT have a fixed value such as unknown_visitor.

      This should be the same identifier as UserEvent.user_pseudo_id and SearchRequest.user_pseudo_id.

      The field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.

    • include_tail_suggestions (::Boolean) (defaults to: nil) —

      Indicates if tail suggestions should be returned if there are no suggestions that match the full query. Even if set to true, if there are suggestions that match the full query, those are returned and no tail suggestions are returned.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.

The configuration is set to the derived mode, meaning that values can be changed, but structural changes (adding new fields, etc.) are not allowed. Structural changes should be made on configure.

See Configuration for a description of the configuration fields.

Yields:

  • (config) —

    Configure the Client client.
