Methods

__construct

Constructor.

Parameters
NameDescription
data array

Optional. Data for populating the Message object.

↳ placement string

Required. The resource name of the Retail Search serving config, such as projects/*/locations/global/catalogs/default_catalog/servingConfigs/default_serving_config or the name of the legacy placement resource, such as projects/*/locations/global/catalogs/default_catalog/placements/default_search. This field is used to identify the serving configuration name and the set of models that will be used to make the search.

↳ 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 page_categories.

↳ visitor_id 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.

↳ user_info Google\Cloud\Retail\V2\UserInfo

User information.

↳ page_size int

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.

↳ page_token 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 int

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 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 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.

↳ 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. 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.

↳ order_by 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.

↳ facet_specs array<Google\Cloud\Retail\V2\SearchRequest\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.

↳ dynamic_facet_spec Google\Cloud\Retail\V2\SearchRequest\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.

↳ boost_spec Google\Cloud\Retail\V2\SearchRequest\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.

↳ query_expansion_spec Google\Cloud\Retail\V2\SearchRequest\QueryExpansionSpec

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

↳ variant_rollup_keys array

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: * colorFamilies * price * originalPrice * discount * variantId * inventory(place_id,price) * inventory(place_id,original_price) * inventory(place_id,attributes.key), where key is any key in the Product.local_inventories.attributes map. * attributes.key, where key is any key in the Product.attributes map. * pickupInStore.id, where id is any FulfillmentInfo.place_ids for FulfillmentInfo.type "pickup-in-store". * shipToStore.id, where id is any FulfillmentInfo.place_ids for FulfillmentInfo.type "ship-to-store". * sameDayDelivery.id, where id is any FulfillmentInfo.place_ids for FulfillmentInfo.type "same-day-delivery". * nextDayDelivery.id, where id is any FulfillmentInfo.place_ids for FulfillmentInfo.type "next-day-delivery". * customFulfillment1.id, where id is any FulfillmentInfo.place_ids for FulfillmentInfo.type "custom-type-1". * customFulfillment2.id, where id is any FulfillmentInfo.place_ids for FulfillmentInfo.type "custom-type-2". * customFulfillment3.id, where id is any FulfillmentInfo.place_ids for FulfillmentInfo.type "custom-type-3". * customFulfillment4.id, where id is any FulfillmentInfo.place_ids for FulfillmentInfo.type "custom-type-4". * customFulfillment5.id, where id is any FulfillmentInfo.place_ids for FulfillmentInfo.type "custom-type-5". If this field is set to an invalid value other than these, an INVALID_ARGUMENT error is returned.

↳ page_categories array

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, please 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"].

↳ search_mode int

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

↳ personalization_spec Google\Cloud\Retail\V2\SearchRequest\PersonalizationSpec
