        # @param [String] name
        #   Required. Full resource name of the format: `name=projects/*/locations/global/
        #   catalogs/default_catalog/eventStores/default_event_store/placements/*` The id
        #   of the recommendation engine placement. This id is used to identify the set of
        #   models that will be used to make the prediction. We currently support three
        #   placements with the following IDs by default: * `shopping_cart`: Predicts
        #   items frequently bought together with one or more catalog items in the same
        #   shopping session. Commonly displayed after `add-to-cart` events, on product
        #   detail pages, or on the shopping cart page. * `home_page`: Predicts the next
        #   product that a user will most likely engage with or purchase based on the
        #   shopping or viewing history of the specified `userId` or `visitorId`. For
        #   example - Recommendations for you. * `product_detail`: Predicts the next
        #   product that a user will most likely engage with or purchase. The prediction
        #   is based on the shopping or viewing history of the specified `userId` or `
        #   visitorId` and its relevance to a specified `CatalogItem`. Typically used on
        #   product detail pages. For example - More items like this. * `
        #   recently_viewed_default`: Returns up to 75 items recently viewed by the
        #   specified `userId` or `visitorId`, most recent ones first. Returns nothing if
        #   neither of them has viewed any items yet. For example - Recently viewed. The

        #   This is a sequence of terms, where each term applies some kind of a
        #   restriction to the returned user events. Use this expression to restrict
        #   results to a specific time range, or filter events by eventType. eg: eventTime
        #   > "2012-04-23T18:25:43.511Z" eventsMissingCatalogItems eventTime<"2012-04-
        #   23T18:25:43.511Z" eventType=search We expect only 3 types of fields: *
        #   eventTime: this can be specified a maximum of 2 times, once with a less than
        #   operator and once with a greater than operator. The eventTime restrict should
        #   result in one contiguous valid eventTime range. * eventType: only 1 eventType
        #   restriction can be specified. * eventsMissingCatalogItems: specififying this
        #   will restrict results to events for which catalog items were not found in the
        #   catalog. The default behavior is to return only those events for which catalog
        #   items were found. Some examples of valid filters expressions: * Example 1:
        #   eventTime > "2012-04-23T18:25:43.511Z" eventTime < "2012-04-23T18:30:43.511Z" *
