Fields
results[]

object (SearchResult)

A list of matched items. The order represents the ranking.
facets[]

object (Facet)

Results of facets requested by user.
totalSize

integer

The estimated total count of matched items irrespective of pagination. The count of results returned by pagination may be less than the totalSize that matches.
correctedQuery

string

Contains the spell corrected query, if found. If the spell correction type is AUTOMATIC, then the search results are based on correctedQuery. Otherwise the original query is used for search.
attributionToken

string

A unique search token. This should be included in the UserEvent logs resulting from this search, which enables accurate attribution of search model performance.
nextPageToken

string

A token that can be sent as SearchRequest.page_token to retrieve the next page. If this field is omitted, there are no subsequent pages.
queryExpansionInfo

object (QueryExpansionInfo)

Query expansion information for the returned results.
redirectUri

string

The URI of a customer-defined redirect page. If redirect action is triggered, no search is performed, and only redirectUri and attributionToken are set in the response.
appliedControls[]

string

The fully qualified resource name of applied controls.
pinControlMetadata

object (PinControlMetadata)

Metadata for pin controls which were applicable to the request. This contains two map fields, one for all matched pins and one for pins which were matched but not applied.

The two maps are keyed by pin position, and the values are the product ids which were matched to that pin.
invalidConditionBoostSpecs[]

object (ConditionBoostSpec)

The invalid SearchRequest.BoostSpec.condition_boost_specs that are not applied during serving.
experimentInfo[]

object (ExperimentInfo)

Metadata related to A/B testing experiment associated with this response. Only exists when an experiment is triggered.
conversationalSearchResult

object (ConversationalSearchResult)

This field specifies all related information that is needed on client side for UI rendering of conversational retail search.
tileNavigationResult

object (TileNavigationResult)

This field specifies all related information for tile navigation that will be used in client side.

SearchResult

Represents the search results.

JSON representation 
{
  "id": string,
  "product": {
    object (Product)
  },
  "matchingVariantCount": integer,
  "matchingVariantFields": {
    string: string,
    ...
  },
  "variantRollupValues": {
    string: value,
    ...
  },
  "personalLabels": [
    string
  ]
}
Fields
id

string

Product.id of the searched Product.
product

object (Product)

The product data snippet in the search response. Only Product.name is guaranteed to be populated.

Product.variants contains the product variants that match the search query. If there are multiple product variants matching the query, top 5 most relevant product variants are returned and ordered by relevancy.

If relevancy can be deternmined, use matchingVariantFields to look up matched product variants fields. If relevancy cannot be determined, e.g. when searching "shoe" all products in a shoe product can be a match, 5 product variants are returned but order is meaningless.
matchingVariantCount

integer

The count of matched variant Products.
matchingVariantFields

map (key: string, value: string (FieldMask format))

If a variant Product matches the search query, this map indicates which Product fields are matched. The key is the Product.name, the value is a field mask of the matched Product fields. If matched attributes cannot be determined, this map will be empty.

For example, a key "sku1" with field mask "products.color_info" indicates there is a match between "sku1" ColorInfo and the query.
variantRollupValues

map (key: string, value: value (Value format))

The rollup matching variant Product attributes. The key is one of the SearchRequest.variant_rollup_keys. The values are the merged and de-duplicated Product attributes. Notice that the rollup values are respect filter. For example, when filtering by "colorFamilies:ANY("red")" and rollup "colorFamilies", only "red" is returned.

For textual and numerical attributes, the rollup values is a list of string or double values with type google.protobuf.ListValue. For example, if there are two variants with colors "red" and "blue", the rollup values are

{ key: "colorFamilies"
  value {
    listValue {
      values { stringValue: "red" }
      values { stringValue: "blue" }
     }
  }
}

For FulfillmentInfo, the rollup values is a double value with type google.protobuf.Value. For example, {key: "pickupInStore.store1" value { numberValue: 10 }} means a there are 10 variants in this product are available in the store "store1".
personalLabels[]

string

Specifies previous events related to this product for this user based on UserEvent with same SearchRequest.visitor_id or UserInfo.user_id.

This is set only when SearchRequest.PersonalizationSpec.mode is SearchRequest.PersonalizationSpec.Mode.AUTO.

Possible values:

  • purchased: Indicates that this product has been purchased before.
