* 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"))

/**
* Use validate only mode for this prediction query. If set to true, a

/**
* 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.

* 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,

* * 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.
