Request message for SearchService.Search method.
Attributes
-
boostSpec
(type:GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestBoostSpec.t
, default:nil
) - Boost specification to boost certain documents. For more information on boosting, see Boosting -
branch
(type:String.t
, default:nil
) - The branch resource name, such asprojects/*/locations/global/collections/default_collection/dataStores/default_data_store/branches/0
. Usedefault_branch
as the branch ID or leave this field empty, to search documents under the default branch. -
canonicalFilter
(type:String.t
, default:nil
) - 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. -
contentSearchSpec
(type:GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestContentSearchSpec.t
, default:nil
) - A specification for configuring the behavior of content search. -
dataStoreSpecs
(type:list(GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestDataStoreSpec.t)
, default:nil
) - 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. -
embeddingSpec
(type:GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestEmbeddingSpec.t
, default:nil
) - Uses the provided embedding to do additional semantic document retrieval. The retrieval is based on the dot product of SearchRequest.EmbeddingSpec.EmbeddingVector.vector and the document embedding that is provided in SearchRequest.EmbeddingSpec.EmbeddingVector.field_path. If SearchRequest.EmbeddingSpec.EmbeddingVector.field_path is not provided, it will use ServingConfig.EmbeddingConfig.field_path. -
facetSpecs
(type:list(GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestFacetSpec.t)
, default:nil
) - Facet specifications for faceted search. If empty, no facets are returned. A maximum of 100 values are allowed. Otherwise, anINVALID_ARGUMENT
error is returned. -
filter
(type:String.t
, default: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, anINVALID_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 -
imageQuery
(type:GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestImageQuery.t
, default:nil
) - Raw image query. -
languageCode
(type:String.t
, default:nil
) - The BCP-47 language code, such as "en-US" or "sr-Latn". For more information, see Standard fields. This field helps to better interpret the query. If a value isn't specified, the query language code is automatically detected, which may not be accurate. -
naturalLanguageQueryUnderstandingSpec
(type:GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestNaturalLanguageQueryUnderstandingSpec.t
, default:nil
) - IfnaturalLanguageQueryUnderstandingSpec
is not specified, no additional natural language query understanding will be done. -
offset
(type:integer()
, default: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, anINVALID_ARGUMENT
is returned. -
orderBy
(type:String.t
, default:nil
) - 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 the website search results, see Order web search results. For more information on ordering the healthcare search results, see Order healthcare search results. If this field is unrecognizable, anINVALID_ARGUMENT
is returned. -
pageSize
(type:integer()
, default:nil
) - 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: Default10
, Maximum25
. Websites with advanced indexing: Default25
, Maximum50
. * Other: Default50
, Maximum100
. If this field is negative, anINVALID_ARGUMENT
is returned. -
pageToken
(type:String.t
, default: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, anINVALID_ARGUMENT
error is returned. -
params
(type:map()
, default: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. For example,user_country_code: "au"
For available codes see Country Codessearch_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
(type:String.t
, default:nil
) - Raw search query. -
queryExpansionSpec
(type:GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestQueryExpansionSpec.t
, default:nil
) - The query expansion specification that specifies the conditions under which query expansion occurs. -
rankingExpression
(type:String.t
, default:nil
) - The ranking expression controls the customized ranking on retrieval documents. This overrides ServingConfig.ranking_expression. The ranking expression is a single function or multiple functions that are joined by "+". ranking_expression = function, { " + ", function }; Supported functions: double relevance_score double dotProduct(embedding_field_path) Function variables:relevance_score
: pre-defined keywords, used for measure relevance between query and document.embedding_field_path
: the document embedding field used with query embedding vector.dotProduct
: embedding function between embedding_field_path and query embedding vector. Example ranking expression: If document has an embedding field doc_embedding, the ranking expression could be0.5 * relevance_score + 0.3 * dotProduct(doc_embedding)
. -
regionCode
(type:String.t
, default:nil
) - The Unicode country/region code (CLDR) of a location, such as "US" and "419". For more information, see Standard fields. If set, then results will be boosted based on the region_code provided. -
relevanceThreshold
(type:String.t
, default:nil
) - The relevance threshold of the search results. Default to Google defined threshold, leveraging a balance of precision and recall to deliver both highly accurate results and comprehensive coverage of relevant information. -
safeSearch
(type:boolean()
, default:nil
) - Whether to turn on safe search. This is only supported for website search. -
searchAsYouTypeSpec
(type:GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestSearchAsYouTypeSpec.t
, default:nil
) - Search as you type configuration. Only supported for the IndustryVertical.MEDIA vertical. -
servingConfig
(type:String.t
, default:nil
) - Required. The resource name of the Search serving config, such asprojects/*/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. -
session
(type:String.t
, default:nil
) - The session resource name. Optional. Session allows users to do multi-turn /search API calls or coordination between /search API calls and /answer API calls. Example #1 (multi-turn /search API calls): 1. Call /search API with the auto-session mode (see below). 2. Call /search API with the session ID generated in the first call. Here, the previous search query gets considered in query standing. I.e., if the first query is "How did Alphabet do in 2022?" and the current query is "How about 2023?", the current query will be interpreted as "How did Alphabet do in 2023?". Example #2 (coordination between /search API calls and /answer API calls): 1. Call /search API with the auto-session mode (see below). 2. Call /answer API with the session ID generated in the first call. Here, the answer generation happens in the context of the search results from the first search call. Auto-session mode: whenprojects/.../sessions/-
is used, a new session gets automatically created. Otherwise, users can use the create-session API to create a session manually. Multi-turn Search feature is currently at private GA stage. Please use v1alpha or v1beta version instead before we launch this feature to public GA. Or ask for allowlisting through Google Support team. -
sessionSpec

) - Session specification. Can be used only whensession
is set. -
spellCorrectionSpec
(type:GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaSearchRequestSpellCorrectionSpec.t
, default:nil
) - The spell correction specification that specifies the mode under which spell correction takes effect. -
userInfo
(type:GoogleApi.DiscoveryEngine.V1beta.Model.GoogleCloudDiscoveryengineV1betaUserInfo.t
, default:nil
) - Information about the end user. Highly recommended for analytics. UserInfo.user_agent is used to deducedevice_type
for analytics. -
userLabels
(type:map()
, default: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. -
userPseudoId
(type:String.t
, default: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 asunknown_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, anINVALID_ARGUMENT
error is returned.
