def search(request, options = nil) -> ::Gapic::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1::SearchResponse::SearchResult>
search
via a request object, either of type
Google::Cloud::DiscoveryEngine::V1::SearchRequest or an equivalent Hash.
- 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, data_store_specs: nil, filter: nil, canonical_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>
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).
-
serving_config (::String) — Required. The resource name of the Search serving config, such as
projects/*/locations/global/collections/default_collection/engines/*/servingConfigs/default_serving_config
, orprojects/*/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. The maximum allowed value depends on the data type. Values above
the maximum value are coerced to the maximum value.
- Websites with basic indexing: Default
10
, Maximum25
. - Websites with advanced indexing: Default
25
, Maximum50
. - Other: Default
50
, Maximum100
.
If this field is negative, an
INVALID_ARGUMENT
is returned. - Websites with basic indexing: Default
-
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. - data_store_specs (::Array<::Google::Cloud::DiscoveryEngine::V1::SearchRequest::DataStoreSpec, ::Hash>) — Specs defining dataStores to filter on in a search call and configurations for those dataStores. This is only considered for engines with multiple dataStores use case. For single dataStore within an engine, they should use the specs at the top level.
-
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.Filtering in Vertex AI Search is done by mapping the LHS filter key to a key property defined in the Vertex AI Search backend -- this mapping is defined by the customer in their schema. For example a media customer might have a field 'name' in their schema. In this case the filter would look like this: filter --> name:'ANY("king kong")'
For more information about filtering including syntax and filter operators, see Filter
-
canonical_filter (::String) — The default filter that is applied when a user performs a search without
checking any filters on the search page.
The filter applied to every search request when quality improvement such as query expansion is needed. In the case a query does not have a sufficient amount of results this filter will be used to determine whether or not to enable the query expansion flow. The original filter will still be used for the query expanded search. This field is strongly recommended to achieve high search quality.
For more information about filter syntax, see SearchRequest.filter.
-
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.For more information on ordering for retail search, see Ordering
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. For more information on boosting, see Boosting
-
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. For example,user_country_code: "au"
For available codes see Country Codes
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. For example,search_type: 1
- 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.
- (response, operation) — Access the result along with the RPC operation
- response (::Gapic::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1::SearchResponse::SearchResult>)
- operation (::GRPC::ActiveCall::Operation)
- (::Gapic::PagedEnumerable<::Google::Cloud::DiscoveryEngine::V1::SearchResponse::SearchResult>)
- (::Google::Cloud::Error) — if the RPC is aborted.
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
