Fields
branch

string

The branch resource name, such as projects/*/locations/global/catalogs/default_catalog/branches/0.

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

query

string

Raw search query.

If this field is empty, the request is considered a category browsing request and returned results are based on filter and pageCategories.

visitorId

string

Required. 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 should be the same identifier as UserEvent.visitor_id.

The field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.

userInfo

object (UserInfo)

User information.

pageSize

integer

Maximum number of Products to return. If unspecified, defaults to a reasonable value. The maximum allowed value is 120. Values above 120 will be coerced to 120.

If this field is negative, an INVALID_ARGUMENT is returned.

pageToken

string

A page token SearchResponse.next_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 Products deemed by the API as relevant) in search results. This field is only considered if pageToken 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 products being filtered. Filter expression is case-sensitive. See more details at this user guide.

If this field is unrecognizable, an INVALID_ARGUMENT is returned.

canonicalFilter

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. For example, if a query does not have enough results, an expanded query with SearchRequest.canonical_filter will be returned as a supplement of the original query. This field is strongly recommended to achieve high search quality.

See SearchRequest.filter for more details about filter syntax.

orderBy

string

The order in which products are returned. Products can be ordered by a field in an Product object. Leave it unset if ordered by relevance. OrderBy expression is case-sensitive. See more details at this user guide.

If this field is unrecognizable, an INVALID_ARGUMENT is returned.

facetSpecs[]

object (FacetSpec)

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.

dynamicFacetSpec
(deprecated)

object (DynamicFacetSpec)

Deprecated. Refer to https://cloud.google.com/retail/docs/configs#dynamic to enable dynamic facets. Do not set this field.

The specification for dynamically generated facets. Notice that only textual facets can be dynamically generated.

boostSpec

object (BoostSpec)

Boost specification to boost certain products. See more details at this user guide.

Notice that if both ServingConfig.boost_control_ids and SearchRequest.boost_spec are set, the boost conditions from both places are evaluated. If a search request matches multiple boost conditions, the final boost score is equal to the sum of the boost scores from all matched boost conditions.

queryExpansionSpec

object (QueryExpansionSpec)

The query expansion specification that specifies the conditions under which query expansion will occur. See more details at this user guide.

variantRollupKeys[]

string

The keys to fetch and rollup the matching variant Products attributes, FulfillmentInfo or LocalInventorys attributes. The attributes from all the matching variant Products or LocalInventorys are merged and de-duplicated. Notice that rollup attributes will lead to extra query latency. Maximum number of keys is 30.

For FulfillmentInfo, a fulfillment type and a fulfillment ID must be provided in the format of "fulfillmentType.fulfillmentId". E.g., in "pickupInStore.store123", "pickupInStore" is fulfillment type and "store123" is the store ID.

Supported keys are:

If this field is set to an invalid value other than these, an INVALID_ARGUMENT error is returned.

pageCategories[]

string

The categories associated with a category page. Required for category navigation queries to achieve good search quality. The format should be the same as UserEvent.page_categories;

To represent full path of category, use '>' sign to separate different hierarchies. If '>' is part of the category name, replace it with other character(s).

Category pages include special pages such as sales or promotions. For instance, a special sale page may have the category hierarchy: "pageCategories" : ["Sales > 2017 Black Friday Deals"].

searchMode

enum (SearchMode)

The search mode of the search request. If not specified, a single search request triggers both product search and faceted search.

personalizationSpec

object (PersonalizationSpec)

The specification for personalization.

Notice that if both ServingConfig.personalization_spec and SearchRequest.personalization_spec are set. SearchRequest.personalization_spec will override ServingConfig.personalization_spec.

labels

map (key: string, value: string)

The 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.

Union field _spell_correction_spec.

_spell_correction_spec can be only one of the following:

spellCorrectionSpec

object (SpellCorrectionSpec)

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

Response body

If successful, the response body contains an instance of SearchResponse.
