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.

#search(request, options = nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse #search(serving_config: nil, branch: nil, 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) ⇒ ::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse

Performs a search.

Overloads:

  • #search(request, options = nil) ⇒ ::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse

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

    Parameters:

    • request (::Google::Cloud::DiscoveryEngine::V1beta::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) (defaults to: nil) —

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

  • #search(serving_config: nil, branch: nil, 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) ⇒ ::Google::Cloud::DiscoveryEngine::V1beta::SearchResponse

    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) (defaults to: nil) —

      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) (defaults to: nil) —

      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) (defaults to: nil) —

      Raw search query.

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

      Maximum number of Documents to return. If unspecified, defaults to a reasonable value. The maximum allowed value is 100. Values above 100 will be coerced to 100.

      If this field is negative, an INVALID_ARGUMENT is returned.

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

      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) (defaults to: nil) —

      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) (defaults to: nil) —

      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) (defaults to: nil) —

      The order in which documents are returned. Document can be ordered by a field in an Document object. Leave it unset if ordered by relevance. OrderBy expression is case-sensitive.

      If this field is unrecognizable, an INVALID_ARGUMENT is returned.

    • user_info (::Google::Cloud::DiscoveryEngine::V1beta::UserInfo, ::Hash) (defaults to: nil) —

      Information about the end user. Highly recommended for analytics. The user_agent string in UserInfo will be used to deduce device_type for analytics.

    • facet_specs (::Array<::Google::Cloud::DiscoveryEngine::V1beta::SearchRequest::FacetSpec, ::Hash>) (defaults to: nil) —

      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::V1beta::SearchRequest::BoostSpec, ::Hash) (defaults to: nil) —

      Boost specification to boost certain documents.

    • params (::Hash{::String => ::Google::Protobuf::Value, ::Hash}) (defaults to: nil) —

      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::V1beta::SearchRequest::QueryExpansionSpec, ::Hash) (defaults to: nil) —

      The query expansion specification that specifies the conditions under which query expansion will occur.

    • spell_correction_spec (::Google::Cloud::DiscoveryEngine::V1beta::SearchRequest::SpellCorrectionSpec, ::Hash) (defaults to: nil) —

      The spell correction specification that specifies the mode under which spell correction will take effect.

    • 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 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::V1beta::SearchRequest::ContentSearchSpec, ::Hash) (defaults to: nil) —

      The content search spec that configs the desired behavior of content search.

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

      Whether to turn on safe search. This is only supported for [ContentConfig.PUBLIC_WEBSITE][].

    • 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:

  • (result, operation) —

    Access the result along with the TransportOperation object

Yield Parameters:

Returns:

Raises:

  • (::Google::Cloud::Error) —

    if the REST call is aborted.
