Instance Method Details

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

Configure the RankService 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.

#rank(request, options = nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::RankResponse #rank(ranking_config: nil, model: nil, top_n: nil, query: nil, records: nil, ignore_record_details_in_response: nil, user_labels: nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::RankResponse

Ranks a list of text records based on the given input query.

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::RankService::Client.new

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

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

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

Overloads:

  • #rank(request, options = nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::RankResponse

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

    Parameters:

    • request (::Google::Cloud::DiscoveryEngine::V1::RankRequest, ::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.

  • #rank(ranking_config: nil, model: nil, top_n: nil, query: nil, records: nil, ignore_record_details_in_response: nil, user_labels: nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1::RankResponse

    Pass arguments to rank 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:

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

      Required. The resource name of the rank service config, such as projects/{project_num}/locations/{location}/rankingConfigs/default_ranking_config.

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

      The identifier of the model to use. It is one of:

      • semantic-ranker-512@latest: Semantic ranking model with maxiumn input token size 512.

      It is set to semantic-ranker-512@latest by default if unspecified.

    • top_n (::Integer) (defaults to: nil) —

      The number of results to return. If this is unset or no bigger than zero, returns all results.

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

      The query to use.

    • records (::Array<::Google::Cloud::DiscoveryEngine::V1::RankingRecord, ::Hash>) (defaults to: nil) —

      Required. A list of records to rank. At most 200 records to rank.

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

      If true, the response will contain only record ID and score. By default, it is false, the response will contain record details.

    • user_labels (::Hash{::String => ::String}) (defaults to: nil) —

      The user labels applied to a resource must meet the following requirements:

      • Each resource can have multiple labels, up to a maximum of 64.
      • Each label must be a key-value pair.
      • Keys have a minimum length of 1 character and a maximum length of 63 characters and cannot be empty. Values can be empty and have a maximum length of 63 characters.
      • Keys and values can contain only lowercase letters, numeric characters, underscores, and dashes. All characters must use UTF-8 encoding, and international characters are allowed.
      • The key portion of a label must be unique. However, you can use the same key with multiple resources.
      • Keys must start with a lowercase letter or international character.

      See Google Cloud Document for more details.

Yields:

  • (response, operation) —

    Access the result along with the RPC operation

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the RPC is aborted.
