Constructor Details

#initialize {|config| ... } ⇒ Client

Create a new SearchService REST client object.

Examples:

Instance Method Details

#configure {|config| ... } ⇒ Client::Configuration

Configure the SearchService Client instance.

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.

Performs a search.

Examples:

Basic example

require "google/cloud/discovery_engine/v1beta"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::DiscoveryEngine::V1beta::SearchService::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::DiscoveryEngine::V1beta::SearchRequest.new

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

# The returned object is of type Gapic::PagedEnumerable. You can iterate
# over elements, and API calls will be issued to fetch pages as needed.
result.each do |item|
  # Each element is of type ::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse::SearchResult.
  p item
end

Overloads:

  • #search(request, options = nil) ⇒ ::Gapic::Rest::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse::SearchResult>

    Pass arguments to search via a request object, either of type Google::Cloud::DiscoveryEngine::V1beta::SearchRequest or an equivalent Hash.

  • #search(serving_config: nil, branch: nil, query: nil, image_query: nil, page_size: nil, page_token: nil, offset: nil, one_box_page_size: nil, data_store_specs: nil, filter: nil, canonical_filter: nil, order_by: nil, user_info: nil, language_code: nil, region_code: nil, facet_specs: nil, boost_spec: nil, params: nil, query_expansion_spec: nil, spell_correction_spec: nil, user_pseudo_id: nil, content_search_spec: nil, embedding_spec: nil, ranking_expression: nil, safe_search: nil, user_labels: nil, natural_language_query_understanding_spec: nil, search_as_you_type_spec: nil, session: nil, session_spec: nil, relevance_threshold: nil, personalization_spec: nil) ⇒ ::Gapic::Rest::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse::SearchResult>

    Pass arguments to search 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).

Yields:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.

Performs a search. Similar to the SearchService.Search method, but a lite version that allows API key for authentication, where OAuth and IAM checks are not required.

Only public website search is supported by this method. If data stores and engines not associated with public website search are specified, a FAILED_PRECONDITION error is returned.

This method can be used for easy onboarding without having to implement an authentication backend. However, it is strongly recommended to use SearchService.Search instead with required OAuth and IAM checks to provide better data security.

Examples:

Basic example

require "google/cloud/discovery_engine/v1beta"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::DiscoveryEngine::V1beta::SearchService::Rest::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::DiscoveryEngine::V1beta::SearchRequest.new

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

# The returned object is of type Gapic::PagedEnumerable. You can iterate
# over elements, and API calls will be issued to fetch pages as needed.
result.each do |item|
  # Each element is of type ::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse::SearchResult.
  p item
end

Overloads:

  • #search_lite(request, options = nil) ⇒ ::Gapic::Rest::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse::SearchResult>

    Pass arguments to search_lite via a request object, either of type Google::Cloud::DiscoveryEngine::V1beta::SearchRequest or an equivalent Hash.

  • #search_lite(serving_config: nil, branch: nil, query: nil, image_query: nil, page_size: nil, page_token: nil, offset: nil, one_box_page_size: nil, data_store_specs: nil, filter: nil, canonical_filter: nil, order_by: nil, user_info: nil, language_code: nil, region_code: nil, facet_specs: nil, boost_spec: nil, params: nil, query_expansion_spec: nil, spell_correction_spec: nil, user_pseudo_id: nil, content_search_spec: nil, embedding_spec: nil, ranking_expression: nil, safe_search: nil, user_labels: nil, natural_language_query_understanding_spec: nil, search_as_you_type_spec: nil, session: nil, session_spec: nil, relevance_threshold: nil, personalization_spec: nil) ⇒ ::Gapic::Rest::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse::SearchResult>

    Pass arguments to search_lite 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).
