user_event

UserEvent

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.

  • (filter_tags: ANY("Red", "Blue")) AND NOT (filter_tags: ANY("Green"))

If attributeFilteringSyntax is set to true under the params field, then attribute-based expressions are expected instead of the above described tag-based syntax. Examples:

  • (launguage: ANY("en", "es")) AND NOT (categories: ANY("Movie"))
  • (available: true) AND (launguage: ANY("en", "es")) OR (categories: ANY("Movie"))

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.

validate_only

bool

Use validate only mode for this recommendation query. If set to true, a fake model will be used that returns arbitrary Document IDs. Note that the validate only mode should only be used for testing the API, or if the model is not ready.

params

map<string, Value>

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.
  • attributeFilteringSyntax: Boolean. False by default. If set to true, the filter field is interpreted according to the new, attribute-based syntax.
user_labels

map<string, string>

The user labels applied to a resource must meet the following requirements:

  • Each resource can have multiple labels, up to a maximum of 64.

Boost specification to boost certain documents.

Fields
condition_boost_specs[]

ConditionBoostSpec

Condition boost specifications. If a document 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.

ConditionBoostSpec

Boost applies to documents which match a condition.

Fields
condition

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 documents with document ID "doc_1" or "doc_2", and color "Red" or "Blue": (document_id: ANY("doc_1", "doc_2")) AND (color: ANY("Red", "Blue"))
boost

float

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 document a big promotion. However, it does not necessarily mean that the boosted document will be the top result at all times, nor that other documents 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 documents.

Setting to -1.0 gives the document a big demotion. However, results that are deeply relevant might still be shown. The document 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. Only one of the (condition, boost) combination or the boost_control_spec below are set. If both are set then the global boost is ignored and the more fine-grained boost_control_spec is applied.

ContentSearchSpec

A specification for configuring the behavior of content search.

Fields
snippet_spec

SnippetSpec

If snippetSpec is not specified, snippets are not included in the search response.

ExtractiveContentSpec

A specification for configuring the extractive content in a search response.

Fields
max_extractive_answer_count

int32

The maximum number of extractive answers returned in each search result.

An extractive answer is a verbatim answer extracted from the original document, which provides a precise and contextually relevant answer to the search query.

If the number of matching answers is less than the max_extractive_answer_count, return all of the answers. Otherwise, return the max_extractive_answer_count.

At most five answers are returned for each SearchResult.

max_extractive_segment_count

int32

The max number of extractive segments returned in each search result. Only applied if the DataStore is set to DataStore.ContentConfig.CONTENT_REQUIRED or DataStore.solution_types is SOLUTION_TYPE_CHAT.

An extractive segment is a text segment extracted from the original document that is relevant to the search query, and, in general, more verbose than an extractive answer. The segment could then be used as input for LLMs to generate summaries and answers.

If the number of matching segments is less than max_extractive_segment_count, return all of the segments. Otherwise, return the max_extractive_segment_count.

return_extractive_segment_score

bool

Specifies whether to return the confidence score from the extractive segments in each search result. This feature is available only for new or allowlisted data stores. To allowlist your data store, contact your Customer Engineer. The default value is false.

(deprecated)

int32

[DEPRECATED] This field is deprecated. To control snippet return, use return_snippet field. For backwards compatibility, we will return snippet if max_snippet_count > 0.

reference_only
(deprecated)

bool

[DEPRECATED] This field is deprecated and will have no affect on the snippet.

return_snippet

bool

If true, then return snippet. If no snippet can be generated, we return "No snippet is available for this page." A snippet_status with SUCCESS or NO_SNIPPET_AVAILABLE will also be returned.

SummarySpec

A specification for configuring a summary returned in a search response.

Fields
summary_result_count

int32

The number of top results to generate the summary from. If the number of results returned is less than summaryResultCount, the summary is generated from all of the results.

At most 10 results for documents mode, or 50 for chunks mode, can be used to generate a summary. The chunks mode is used when [SearchRequest.ContentSearchSpec.search_result_mode][] is set to [CHUNKS][SearchRequest.ContentSearchSpec.SearchResultMode.CHUNKS].

include_citations

bool

Specifies whether to include citations in the summary. The default value is false.

When this field is set to true, summaries include in-line citation numbers.

Example summary including citations:

BigQuery is Google Cloud's fully managed and completely serverless enterprise data warehouse [1]. BigQuery supports all data types, works across clouds, and has built-in machine learning and business intelligence, all within a unified platform [2, 3].

The citation numbers refer to the returned search results and are 1-indexed. For example, [1] means that the sentence is attributed to the first search result. [2, 3] means that the sentence is attributed to both the second and third search results.

ignore_adversarial_query

bool

Specifies whether to filter out adversarial queries. The default value is false.

Google employs search-query classification to detect adversarial queries. No summary is returned if the search query is classified as an adversarial query. For example, a user might ask a question regarding negative comments about the company or submit a query designed to generate unsafe, policy-violating output. If this field is set to true, we skip generating summaries for adversarial queries and return fallback messages instead.

ignore_non_summary_seeking_query

bool

Specifies whether to filter out queries that are not summary-seeking. The default value is false.

Google employs search-query classification to detect summary-seeking queries. No summary is returned if the search query is classified as a non-summary seeking query. For example, why is the sky blue and Who is the best soccer player in the world? are summary-seeking queries, but SFO airport and world cup 2026 are not. They are most likely navigational queries. If this field is set to true, we skip generating summaries for non-summary seeking queries and return fallback messages instead.

model_prompt_spec

ModelPromptSpec

If specified, the spec will be used to modify the prompt provided to the LLM.

language_code

string

Language code for Summary. Use language tags defined by BCP47. Note: This is an experimental feature.

model_spec

ModelSpec

If specified, the spec will be used to modify the model specification provided to the LLM.

use_semantic_chunks

bool

If true, answer will be generated from most relevant chunks from top search results. This feature will improve summary quality. Note that with this feature enabled, not all top search results will be referenced and included in the reference list, so the citation source index only points to the search results listed in the reference list.

ModelPromptSpec

Fields
preamble

string

Text at the beginning of the prompt that instructs the assistant. Examples are available in the user guide.

ModelSpec

Specification of the model.

Fields

Supported values are:

DataStoreSpec

A struct to define data stores to filter on in a search call.

Fields
data_store

string

Required. Full resource name of DataStore, such as projects/{project}/locations/{location}/collections/{collection_id}/dataStores/{data_store_id}.

FacetSpec

A facet specification to perform faceted search.

Fields
facet_key

FacetKey

Required. The facet key specification.

limit

int32

Maximum of facet values that should be returned for this facet. If unspecified, defaults to 20. The maximum allowed value is 300. Values above 300 are coerced to 300.

If this field is negative, an INVALID_ARGUMENT is returned.

excluded_filter_keys[]

string

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 documents with the color facet "Red" and 200 documents with the color facet "Blue". A query containing the filter "color:ANY("Red")" and having "color" as FacetKey.key would by default return only "Red" documents in the search results, and also return "Red" with count 100 as the only color facet. Although there are also blue documents available, "Blue" would not be shown as an available facet value.

If "color" is listed in "excludedFilterKeys", then the query returns the facet values "Red" with count 100 and "Blue" with count 200, because the "color" 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" documents.

A maximum of 100 values are allowed. Otherwise, an INVALID_ARGUMENT error is returned.

enable_dynamic_position

bool

Enables dynamic position for this facet. If set to true, the position of this facet among all facets in the response is determined automatically. If dynamic facets are enabled, it is ordered together. 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 automatically.

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 enabled, 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 API orders "gender" and "rating" facets. However, notice that "price" and "brands" are always ranked at first and second position because their enable_dynamic_position is false.

string

Required. Supported textual and numerical facet keys in Document object, over which the facet values are computed. Facet key is case-sensitive.

prefixes[]

string

Only get facet values that start with the given string prefix. For example, suppose "category" has three values "Action > 2022", "Action > 2021" and "Sci-Fi > 2022". If set "prefixes" to "Action", the "category" facet only contains "Action > 2022" and "Action > 2021". Only supported on textual fields. Maximum is 10.

contains[]

string

Only get facet values that contains the given strings. For example, suppose "category" has three values "Action > 2022", "Action > 2021" and "Sci-Fi > 2022". If set "contains" to "2022", the "category" facet only contains "Action > 2022" and "Sci-Fi > 2022". Only supported on textual fields. Maximum is 10.

user_pseudo_id

string

Required. A unique identifier for tracking visitors.

For example, this could be implemented with an HTTP cookie, which should be able to uniquely identify a visitor on a single device. This unique identifier should not change if the visitor log in/out of the website.

Do not set the field to the same fixed ID for different users. This mixes the event history of those users together, which results in degraded model quality.

The field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.

The field should not contain PII or user-data. We recommend to use Google Analytics Client ID for this field.

event_time

Timestamp

Only required for UserEventService.ImportUserEvents method. Timestamp of when the user event happened.

user_info

UserInfo

Information about the end user.

direct_user_request

bool

Should set to true if the request is made directly from the end user, in which case the UserEvent.user_info.user_agent can be populated from the HTTP request.

This flag should be set only if the API request is made directly from the end user such as a mobile app (and not if a gateway or a server is processing and pushing the user events).

This should not be set when using the JavaScript tag in UserEventService.CollectUserEvent.

session_id

string

A unique identifier for tracking a visitor session with a length limit of 128 bytes. A session is an aggregation of an end user behavior in a time span.

A general guideline to populate the session_id:

  1. If user has no activity for 30 min, a new session_id should be assigned.
  2. The session_id should be unique across users, suggest use uuid or add UserEvent.user_pseudo_id as prefix.
page_info

PageInfo

Page metadata such as categories and other critical information for certain event types such as view-category-page.

attribution_token

string

Token to attribute an API response to user action(s) to trigger the event.

Highly recommended for user events that are the result of RecommendationService.Recommend. This field enables accurate attribution of recommendation model performance.

The value must be one of:

This token enables us to accurately attribute page view or conversion completion 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 RecommendResponse.attribution_token as a URL parameter to product K's page. When recording events on product K's page, log the RecommendResponse.attribution_token to this field.

filter

string

The filter syntax consists of an expression language for constructing a predicate from one or more fields of the documents being filtered.

One example is for search events, the associated SearchRequest may contain a filter expression in SearchRequest.filter conforming to https://google.aip.dev/160#filtering.

Similarly, for view-item-list events that are generated from a RecommendRequest, this field may be populated directly from RecommendRequest.filter conforming to https://google.aip.dev/160#filtering.

The value must be a UTF-8 encoded string with a length limit of 1,000 characters. Otherwise, an INVALID_ARGUMENT error is returned.

documents[]

DocumentInfo

List of Documents associated with this user event.

This field is optional except for the following event types:

  • view-item
  • add-to-cart
  • purchase
  • media-play
  • media-complete

In a search event, this field represents the documents 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 UserEvent.documents is desired.

panel

PanelInfo

Panel metadata associated with this user event.

search_info

SearchInfo

SearchService.Search details related to the event.

This field should be set for search event.

completion_info

CompletionInfo

CompletionService.CompleteQuery details related to the event.

This field should be set for search event when autocomplete function is enabled and the user clicks a suggestion for search.

transaction_info

TransactionInfo

The transaction metadata (if any) associated with this user event.

tag_ids[]

string

A list of identifiers for the independent experiment groups this user event belongs to. This is used to distinguish between user events associated with different experiment setups on the customer end.

promotion_ids[]

string

The promotion IDs if this is an event associated with promotions. Currently, this field is restricted to at most one ID.

attributes

map<string, CustomAttribute>

Extra user event features to include in the recommendation model. These attributes must NOT contain data that needs to be parsed or processed further, e.g. JSON or other encodings.

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 Discovery Engine 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.

media_info

MediaInfo

Media-specific info.

UserInfo

Information of an end user.

Fields
user_id

string

Highly recommended for logged-in users. Unique identifier for logged-in user, such as a user name. Don't set for anonymous users.

Always use a hashed value for this ID.

Don't set the field to the same fixed ID for different users. This mixes the event history of those users together, which results in degraded model quality.

The field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.

user_agent

string

User agent as included in the HTTP header.

The field must be a UTF-8 encoded string with a length limit of 1,000 characters. Otherwise, an INVALID_ARGUMENT error is returned.

This should not be set when using the client side event reporting with GTM or JavaScript tag in UserEventService.CollectUserEvent or if UserEvent.direct_user_request is set.

Request message for WriteUserEvent method.

Fields
parent

string

Required. The parent resource name. If the write user event action is applied in DataStore level, the format is: projects/{project}/locations/{location}/collections/{collection}/dataStores/{data_store}. If the write user event action is applied in [Location][] level, for example, the event with Document across multiple DataStore, the format is: projects/{project}/locations/{location}.

user_event

UserEvent

Required. User event to write.
