Yields
  • (config) — Configure the Client client.
Yield Parameter
Returns
Example 
# Modify the configuration for all SearchService clients
::Google::Cloud::DiscoveryEngine::V1::SearchService::Client.configure do |config|
  config.timeout = 10.0
end

#configure

def configure() { |config| ... } -> Client::Configuration

  • (config) — Configure the SearchService client.
Yield Parameter
Returns
  • (Client) — a new instance of Client
Example 
# Create a client using the default configuration
client = ::Google::Cloud::DiscoveryEngine::V1::SearchService::Client.new

# Create a client using a custom configuration
client = ::Google::Cloud::DiscoveryEngine::V1::SearchService::Client.new do |config|
  config.timeout = 10.0

#search

def search(request, options = nil) -> ::Gapic::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1::SearchResponse::SearchResult>
def search(serving_config: nil, branch: nil, query: nil, image_query: nil, page_size: nil, page_token: nil, offset: nil, filter: nil, order_by: nil, user_info: 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, safe_search: nil, user_labels: nil) -> ::Gapic::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1::SearchResponse::SearchResult>

Performs a search.

Overloads 
def search(request, options = nil) -> ::Gapic::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1::SearchResponse::SearchResult>
Pass arguments to search via a request object, either of type Google::Cloud::DiscoveryEngine::V1::SearchRequest or an equivalent Hash.
Parameters
  • request (::Google::Cloud::DiscoveryEngine::V1::SearchRequest, ::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) — Overrides the default settings for this call, e.g, timeout, retries, etc. Optional. 
def search(serving_config: nil, branch: nil, query: nil, image_query: nil, page_size: nil, page_token: nil, offset: nil, filter: nil, order_by: nil, user_info: 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, safe_search: nil, user_labels: nil) -> ::Gapic::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1::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).
Parameters
  • serving_config (::String) — Required. The resource name of the Search serving config, such as projects/*/locations/global/collections/default_collection/dataStores/default_data_store/servingConfigs/default_serving_config. This field is used to identify the serving configuration name, set of models used to make the search.
  • branch (::String) — The branch resource name, such as projects/*/locations/global/collections/default_collection/dataStores/default_data_store/branches/0.

    Use default_branch as the branch ID or leave this field empty, to search documents under the default branch.

  • query (::String) — Raw search query.
  • image_query (::Google::Cloud::DiscoveryEngine::V1::SearchRequest::ImageQuery, ::Hash) — Raw image query.
  • page_size (::Integer) — Maximum number of Documents to return. If unspecified, defaults to a reasonable value. The maximum allowed value is 100. Values above 100 are coerced to 100.

    If this field is negative, an INVALID_ARGUMENT is returned.

  • page_token (::String) — A page token received from a previous SearchService.Search call. Provide this to retrieve the subsequent page.

    When paginating, all other parameters provided to SearchService.Search must match the call that provided the page token. Otherwise, an INVALID_ARGUMENT error is returned.

  • offset (::Integer) — A 0-indexed integer that specifies the current offset (that is, starting result location, amongst the Documents deemed by the API as relevant) in search results. This field is only considered if page_token is unset.

    If this field is negative, an INVALID_ARGUMENT is returned.

  • filter (::String) — The filter syntax consists of an expression language for constructing a predicate from one or more fields of the documents being filtered. Filter expression is case-sensitive.

    If this field is unrecognizable, an INVALID_ARGUMENT is returned.

  • order_by (::String) — The order in which documents are returned. Documents can be ordered by a field in an Document object. Leave it unset if ordered by relevance. order_by expression is case-sensitive.

    If this field is unrecognizable, an INVALID_ARGUMENT is returned.

  • user_info (::Google::Cloud::DiscoveryEngine::V1::UserInfo, ::Hash) — Information about the end user. Highly recommended for analytics. UserInfo.user_agent is used to deduce device_type for analytics.
  • facet_specs (::Array<::Google::Cloud::DiscoveryEngine::V1::SearchRequest::FacetSpec, ::Hash>) — Facet specifications for faceted search. If empty, no facets are returned.

    A maximum of 100 values are allowed. Otherwise, an INVALID_ARGUMENT error is returned.

  • boost_spec (::Google::Cloud::DiscoveryEngine::V1::SearchRequest::BoostSpec, ::Hash) — Boost specification to boost certain documents.
  • params (::Hash{::String => ::Google::Protobuf::Value, ::Hash}) —

    Additional search parameters.

    For public website search only, supported values are:

    • user_country_code: string. Default empty. If set to non-empty, results are restricted or boosted based on the location provided.
    • search_type: double. Default empty. Enables non-webpage searching depending on the value. The only valid non-default value is 1, which enables image searching.
  • query_expansion_spec (::Google::Cloud::DiscoveryEngine::V1::SearchRequest::QueryExpansionSpec, ::Hash) — The query expansion specification that specifies the conditions under which query expansion occurs.
  • spell_correction_spec (::Google::Cloud::DiscoveryEngine::V1::SearchRequest::SpellCorrectionSpec, ::Hash) — The spell correction specification that specifies the mode under which spell correction takes effect.
  • user_pseudo_id (::String) — 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 CompleteQueryRequest.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.

  • content_search_spec (::Google::Cloud::DiscoveryEngine::V1::SearchRequest::ContentSearchSpec, ::Hash) — A specification for configuring the behavior of content search.
  • safe_search (::Boolean) — Whether to turn on safe search. This is only supported for website search.
  • user_labels (::Hash{::String => ::String}) — 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.
Example

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::SearchService::Client.new

# Create a request. To set request fields, pass in keyword arguments.
request = Google::Cloud::DiscoveryEngine::V1::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::V1::SearchResponse::SearchResult.
  p item
end
