Methods

containsParams(String key)

public abstract boolean containsParams(String key)

Additional domain specific parameters for the recommendations.

Allowed values:

returnDocument: Boolean. If set to true, the associated Document object will be returned in RecommendResponse.RecommendationResult.document.
returnScore: Boolean. If set to true, the recommendation 'score' corresponding to each returned Document will be set in RecommendResponse.RecommendationResult.metadata. The given 'score' indicates the probability of a Document conversion given the user's context and history.
strictFiltering: Boolean. True by default. If set to false, the service will return generic (unfiltered) popular Documents instead of empty if your filter blocks all recommendation results.
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 recommendation results based on Document category.

map<string, .google.protobuf.Value> params = 6;

Parameter
Name	Description
`key`	`String`

Returns
Type	Description
`boolean`

containsUserLabels(String key)

public abstract boolean containsUserLabels(String key)

The user 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 Requirements for labels for more details.

map<string, string> user_labels = 8;

Parameter
Name	Description
`key`	`String`

Returns
Type	Description
`boolean`

getFilter()

public abstract String getFilter()

Filter for restricting recommendation results with a length limit of 5,000 characters. Currently, only filter expressions on the filter_tags attribute is supported.

Examples:

(filter_tags: ANY("Red", "Blue") OR filter_tags: ANY("Hot", "Cold"))
(filter_tags: ANY("Red", "Blue")) AND NOT (filter_tags: ANY("Green"))

If your filter blocks all results, the API will return generic (unfiltered) popular Documents. If you only want results strictly matching the filters, set strictFiltering to True in RecommendRequest.params to receive empty results instead.

Note that the API will never return Documents with storageStatus of EXPIRED or DELETED regardless of filter choices.

string filter = 4;

Returns
Type	Description
`String`	The filter.

getFilterBytes()

public abstract ByteString getFilterBytes()

Filter for restricting recommendation results with a length limit of 5,000 characters. Currently, only filter expressions on the filter_tags attribute is supported.

Examples:

(filter_tags: ANY("Red", "Blue") OR filter_tags: ANY("Hot", "Cold"))
(filter_tags: ANY("Red", "Blue")) AND NOT (filter_tags: ANY("Green"))

If your filter blocks all results, the API will return generic (unfiltered) popular Documents. If you only want results strictly matching the filters, set strictFiltering to True in RecommendRequest.params to receive empty results instead.

Note that the API will never return Documents with storageStatus of EXPIRED or DELETED regardless of filter choices.

string filter = 4;

Returns
Type	Description
`ByteString`	The bytes for filter.

getPageSize()

public abstract int getPageSize()

Returns
Type	Description
`int`	The pageSize.

getServingConfig()

public abstract String getServingConfig()

Required. Full resource name of the format: projects/*/locations/global/collections/*/dataStores/*/servingConfigs/*

Before you can request recommendations from your model, you must create at least one serving config for it.

string serving_config = 1 [(.google.api.field_behavior) = REQUIRED, (.google.api.resource_reference) = { ... }

Returns
Type	Description
`String`	The servingConfig.

getServingConfigBytes()

public abstract ByteString getServingConfigBytes()

Required. Full resource name of the format: projects/*/locations/global/collections/*/dataStores/*/servingConfigs/*

Before you can request recommendations from your model, you must create at least one serving config for it.

getUserEvent()

public abstract UserEvent getUserEvent()

Required. Context about the user, what they are looking at and what action they took to trigger the Recommend 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.user_pseudo_id or UserEvent.user_info.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.user_pseudo_id to a random unique ID and leave UserEvent.user_info.user_id unset.

Returns
Type	Description
`UserEvent`	The userEvent.
