predict(placement, body=None, x__xgafv=None)

Makes a recommendation prediction.

Args:
  placement: string, Required. Full resource name of the format: `{placement=projects/*/locations/global/catalogs/default_catalog/servingConfigs/*}` or `{placement=projects/*/locations/global/catalogs/default_catalog/placements/*}`. We recommend using the `servingConfigs` resource. `placements` is a legacy resource. The ID of the Recommendations AI serving config or placement. Before you can request predictions from your model, you must create at least one serving config or placement for it. For more information, see [Manage serving configs] (https://cloud.google.com/retail/docs/manage-configs). The full list of available serving configs can be seen at https://console.cloud.google.com/ai/retail/catalogs/default_catalog/configs (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for Predict method.
  "filter": "A String", # Filter for restricting prediction results with a length limit of 5,000 characters. Accepts values for tags and the `filterOutOfStockItems` flag. * Tag expressions. Restricts predictions to products that match all of the specified tags. Boolean operators `OR` and `NOT` are supported if the expression is enclosed in parentheses, and must be separated from the tag values by a space. `-"tagA"` is also supported and is equivalent to `NOT "tagA"`. Tag values must be double quoted UTF-8 encoded strings with a size limit of 1,000 characters. Note: "Recently viewed" models don't support tag filtering at the moment. * filterOutOfStockItems. Restricts predictions to products that do not have a stockState value of OUT_OF_STOCK. Examples: * tag=("Red" OR "Blue") tag="New-Arrival" tag=(NOT "promotional") * filterOutOfStockItems tag=(-"promotional") * filterOutOfStockItems If your filter blocks all prediction results, the API will return *no* results. If instead you want empty result sets to return generic (unfiltered) popular products, set `strictFiltering` to False in `PredictRequest.params`. Note that the API will never return items with storageStatus of "EXPIRED" or "DELETED" regardless of filter choices. If `filterSyntaxV2` is set to true under the `params` field, then attribute-based expressions are expected instead of the above described tag-based syntax. Examples: * (colors: ANY("Red", "Blue")) AND NOT (categories: ANY("Phones")) * (availability: ANY("IN_STOCK")) AND (colors: ANY("Red") OR categories: ANY("Phones")) For more information, see [Filter recommendations](https://cloud.google.com/retail/docs/filter-recs).
  "labels": { # 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](https://cloud.google.com/resource-manager/docs/creating-managing-labels#requirements) for more details.
    "a_key": "A String",
  },
  "pageSize": 42, # Maximum number of results to return. Set this property to the number of prediction results needed. If zero, the service will choose a reasonable default. The maximum allowed value is 100. Values above 100 will be coerced to 100.
  "pageToken": "A String", # This field is not used; leave it unset.
  "params": { # Additional domain specific parameters for the predictions. Allowed values: * `returnProduct`: Boolean. If set to true, the associated product object will be returned in the `results.metadata` field in the prediction response. * `returnScore`: Boolean. If set to true, the prediction 'score' corresponding to each returned product will be set in the `results.metadata` field in the prediction response. The given 'score' indicates the probability of a product being clicked/purchased given the user's context and history. * `strictFiltering`: Boolean. True by default. If set to false, the service will return generic (unfiltered) popular products instead of empty if your filter blocks all prediction results. * `priceRerankLevel`: String. Default empty. If set to be non-empty, then it needs to be one of {'no-price-reranking', 'low-price-reranking', 'medium-price-reranking', 'high-price-reranking'}. This gives request-level control and adjusts prediction results based on product price. * `diversityLevel`: String. Default empty. If set to be non-empty, then it needs to be one of {'no-diversity', 'low-diversity', 'medium-diversity', 'high-diversity', 'auto-diversity'}. This gives request-level control and adjusts prediction results based on product category. * `filterSyntaxV2`: Boolean. False by default. If set to true, the `filter` field is interpreteted according to the new, attribute-based syntax.

  "userEvent": { # UserEvent captures all metadata information Retail API needs to know about how end users interact with customers' website. # Required. Context about the user, what they are looking at and what action they took to trigger the predict request. Note that this user event detail won't be ingested to userEvent logs. Thus, a separate userEvent write request is required for event logging. Don't set UserEvent.visitor_id or UserInfo.user_id to the same fixed ID for different users. If you are trying to receive non-personalized recommendations (not recommended; this can negatively impact model performance), instead set UserEvent.visitor_id to a random unique ID and leave UserInfo.user_id unset.
    "attributes": { # Extra user event features to include in the recommendation model. If you provide custom attributes for ingested user events, also include them in the user events that you associate with prediction requests. Custom attribute formatting must be consistent between imported events and events provided with prediction requests. This lets the Retail API use those custom attributes when training models and serving predictions, which helps improve recommendation quality. This field needs to pass all below criteria, otherwise an INVALID_ARGUMENT error is returned: * The key must be a UTF-8 encoded string with a length limit of 5,000 characters. * For text attributes, at most 400 values are allowed. Empty values are not allowed. Each value must be a UTF-8 encoded string with a length limit of 256 characters. * For number attributes, at most 400 values are allowed. For product recommendations, an example of extra user information is traffic_channel, which is how a user arrives at the site. Users can arrive at the site by coming to the site directly, coming through Google search, or in other ways.

The value must be a valid PredictResponse.attribution_token for user events that are the result of PredictionService.Predict. The value must be a valid SearchResponse.attribution_token for user events that are the result of SearchService.Search. This token enables us to accurately attribute page view or purchase back to the event and the particular predict response containing this clicked/purchased product. If user clicks on product K in the recommendation results, pass PredictResponse.attribution_token as a URL parameter to product K's page. When recording events on product K's page, log the PredictResponse.attribution_token to this field.
    "cartId": "A String", # The ID or name of the associated shopping cart. This ID is used to associate multiple items added or present in the cart before purchase. This can only be set for `add-to-cart`, `purchase-complete`, or `shopping-cart-page-view` events.

    "pageViewId": "A String", # A unique ID of a web page view. This should be kept the same for all user events triggered from the same pageview. For example, an item detail page view could trigger multiple events as the user is browsing the page. The `pageViewId` property should be kept the same for all these events so that they can be grouped together properly. When using the client side event reporting with JavaScript pixel and Google Tag Manager, this value is filled in automatically.
    "productDetails": [ # The main product details related to the event. This field is optional except for the following event types: * `add-to-cart` * `detail-page-view` * `purchase-complete` In a `search` event, this field represents the products returned to the end user on the current page (the end user may have not finished browsing the whole page yet). When a new page is returned to the end user, after pagination/filtering/ordering even for the same query, a new `search` event with different product_details is desired. The end user may have not finished browsing the whole page yet.

search(placement, body=None, x__xgafv=None)

Performs a search. This feature is only available for users who have Retail Search enabled. Enable Retail Search on Cloud Console before using this feature.

Args:
  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 config name and the set of models that are used to make the search. (required)
  body: object, The request body.
    The object takes the form of:

{ # Request message for SearchService.Search method.
  "boostSpec": { # Boost specification to boost certain items. # Boost specification to boost certain products. For more information, see [Boost results](https://cloud.google.com/retail/docs/boosting). 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.
    "conditionBoostSpecs": [ # Condition boost specifications. If a product matches multiple conditions in the specifictions, boost scores from these specifications are all applied and combined in a non-linear way. Maximum number of specifications is 20.
      { # Boost applies to products which match a condition.
        "boost": 3.14, # Strength of the condition boost, which should be in [-1, 1]. Negative boost means demotion. Default is 0.0. Setting to 1.0 gives the item a big promotion. However, it does not necessarily mean that the boosted item will be the top result at all times, nor that other items will be excluded. Results could still be shown even when none of them matches the condition. And results that are significantly more relevant to the search query can still trump your heavily favored but irrelevant items. Setting to -1.0 gives the item a big demotion. However, results that are deeply relevant might still be shown. The item will have an upstream battle to get a fairly high ranking, but it is not blocked out completely. Setting to 0.0 means no boost applied. The boosting condition is ignored.
        "condition": "A String", # An expression which specifies a boost condition. The syntax and supported fields are the same as a filter expression. See SearchRequest.filter for detail syntax and limitations. Examples: * To boost products with product ID "product_1" or "product_2", and color "Red" or "Blue": * (id: ANY("product_1", "product_2")) AND (colorFamilies: ANY("Red","Blue"))
      },
    ],
    "skipBoostSpecValidation": True or False, # Whether to skip boostspec validation. If this field is set to true, invalid BoostSpec.condition_boost_specs will be ignored and valid BoostSpec.condition_boost_specs will still be applied.
  },
  "branch": "A 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.
  "canonicalFilter": "A 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.
  "conversationalSearchSpec": { # This field specifies all conversational related parameters addition to traditional retail search. # Optional. This field specifies all conversational related parameters addition to traditional retail search.
    "conversationId": "A String", # This field specifies the conversation id, which maintains the state of the conversation between client side and server side. Use the value from the previous ConversationalSearchResult.conversation_id. For the initial request, this should be empty.
    "followupConversationRequested": True or False, # This field specifies whether the customer would like to do conversational search. If this field is set to true, conversational related extra information will be returned from server side, including follow-up question, answer options, etc.
    "userAnswer": { # This field specifies the current user answer during the conversational search. This can be either user selected from suggested answers or user input plain text. # This field specifies the current user answer during the conversational search. This can be either user selected from suggested answers or user input plain text.
      "selectedAnswer": { # This field specifies the selected answers during the conversational search. # This field specifies the selected attributes during the conversational search. This should be a subset of ConversationalSearchResult.suggested_answers.
        "productAttributeValue": { # Product attribute which structured by an attribute name and value. This structure is used in conversational search filters and answers. For example, if we have `name=color` and `value=red`, this means that the color is `red`. # This field specifies the selected answer which is a attribute key-value.
          "name": "A String", # The attribute name.
          "value": "A String", # The attribute value.
        },

    },
  },
  "dynamicFacetSpec": { # The specifications of dynamically generated facets. # 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.
    "mode": "A String", # Mode of the DynamicFacet feature. Defaults to Mode.DISABLED if it's unset.
  },
  "entity": "A String", # The entity for customers that may run multiple different entities, domains, sites or regions, for example, `Google US`, `Google Ads`, `Waymo`, `google.com`, `youtube.com`, etc. If this is set, it should be exactly matched with UserEvent.entity to get search results boosted by entity.
  "facetSpecs": [ # Facet specifications for faceted search. If empty, no facets are returned. A maximum of 200 values are allowed. Otherwise, an INVALID_ARGUMENT error is returned.
    { # A facet specification to perform faceted search.
      "enableDynamicPosition": True or False, # Enables dynamic position for this facet. If set to true, the position of this facet among all facets in the response is determined by Google Retail Search. It is ordered together with dynamic facets if dynamic facets is enabled. If set to false, the position of this facet in the response is the same as in the request, and it is ranked before the facets with dynamic position enable and all dynamic facets. For example, you may always want to have rating facet returned in the response, but it's not necessarily to always display the rating facet at the top. In that case, you can set enable_dynamic_position to true so that the position of rating facet in response is determined by Google Retail Search. Another example, assuming you have the following facets in the request: * "rating", enable_dynamic_position = true * "price", enable_dynamic_position = false * "brands", enable_dynamic_position = false And also you have a dynamic facets enable, which generates a facet "gender". Then, the final order of the facets in the response can be ("price", "brands", "rating", "gender") or ("price", "brands", "gender", "rating") depends on how Google Retail Search orders "gender" and "rating" facets. However, notice that "price" and "brands" are always ranked at first and second position because their enable_dynamic_position values are false.
      "excludedFilterKeys": [ # List of keys to exclude when faceting. By default, FacetKey.key is not excluded from the filter unless it is listed in this field. Listing a facet key in this field allows its values to appear as facet results, even when they are filtered out of search results. Using this field does not affect what search results are returned. For example, suppose there are 100 products with the color facet "Red" and 200 products with the color facet "Blue". A query containing the filter "colorFamilies:ANY("Red")" and having "colorFamilies" as FacetKey.key would by default return only "Red" products in the search results, and also return "Red" with count 100 as the only color facet. Although there are also blue products available, "Blue" would not be shown as an available facet value. If "colorFamilies" is listed in "excludedFilterKeys", then the query returns the facet values "Red" with count 100 and "Blue" with count 200, because the "colorFamilies" key is now excluded from the filter. Because this field doesn't affect search results, the search results are still correctly filtered to return only "Red" products. A maximum of 100 values are allowed. Otherwise, an INVALID_ARGUMENT error is returned.

Maximum number of intervals is 40. For all numerical facet keys that appear in the list of products from the catalog, the percentiles 0, 10, 30, 50, 70, 90, and 100 are computed from their distribution weekly. If the model assigns a high score to a numerical facet key and its intervals are not specified in the search request, these percentiles become the bounds for its intervals and are returned in the response. If the facet key intervals are specified in the request, then the specified intervals are returned instead.

In the response, SearchResponse.Facet.values.value is always "1" and SearchResponse.Facet.values.count is the number of results that match the query. For example, you can set a customized facet for "shipToStore", where FacetKey.key is "customizedShipToStore", and FacetKey.query is "availability: ANY(\"IN_STOCK\") AND shipToStore: ANY(\"123\")". Then the facet counts the products that are both in stock and ship to store "123".
