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.

This feature is only available for users who have Retail Search enabled. Enable Retail Search on Cloud Console before using this feature.

Examples:

Basic example

require "google/cloud/retail/v2"

# Create a client object. The client can be reused for multiple calls.
client = Google::Cloud::Retail::V2::SearchService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::Retail::V2::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::Retail::V2::SearchResponse::SearchResult.
  p item
end

Overloads:

  • #search(request, options = nil) ⇒ ::Gapic::PagedEnumerable<::Google::Cloud::Retail::V2::SearchResponse::SearchResult>

    Pass arguments to search via a request object, either of type Google::Cloud::Retail::V2::SearchRequest or an equivalent Hash.

  • #search(placement: nil, branch: nil, query: nil, visitor_id: nil, user_info: nil, page_size: nil, page_token: nil, offset: nil, filter: nil, canonical_filter: nil, order_by: nil, facet_specs: nil, dynamic_facet_spec: nil, boost_spec: nil, query_expansion_spec: nil, variant_rollup_keys: nil, page_categories: nil, search_mode: nil, personalization_spec: nil, labels: nil, spell_correction_spec: nil, entity: nil, conversational_search_spec: nil, tile_navigation_spec: nil, language_code: nil, region_code: nil, place_id: nil, user_attributes: nil) ⇒ ::Gapic::PagedEnumerable<::Google::Cloud::Retail::V2::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:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
