RankResponse

Response message for RankService.Rank method.

Fields
records[]	RankingRecord A list of records sorted by descending score.

RankingRecord

Record message for RankService.Rank method.

Fields
id	string The unique ID to represent the record.
title	string The title of the record. Empty by default. At least one of title or content should be set otherwise an INVALID_ARGUMENT error is thrown.
content	string The content of the record. Empty by default. At least one of title or content should be set otherwise an INVALID_ARGUMENT error is thrown.
score	float The score of this record based on the given query and selected model. The score will be rounded to 2 decimal places. If the score is close to 0, it will be rounded to 0.0001 to avoid returning unset.

RecommendRequest

Request message for Recommend method.

Fields
serving_config	string Required. Full resource name of a ServingConfig: projects/*/locations/global/collections/*/engines/*/servingConfigs/*, or projects/*/locations/global/collections/*/dataStores/*/servingConfigs/* One default serving config is created along with your recommendation engine creation. The engine ID is used as the ID of the default serving config. For example, for Engine projects/*/locations/global/collections/*/engines/my-engine, you can use projects/*/locations/global/collections/*/engines/my-engine/servingConfigs/my-engine for your RecommendationService.Recommend requests.
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.
page_size	int32 Maximum number of results to return. Set this property to the number of recommendation results needed. If zero, the service chooses a reasonable default. The maximum allowed value is 100. Values above 100 are set to 100.
filter	string 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 attributeFilteringSyntax is set to true under the params field, then attribute-based expressions are expected instead of the above described tag-based syntax. Examples: (language: ANY("en", "es")) AND NOT (categories: ANY("Movie")) (available: true) AND (language: ANY("en", "es")) OR (categories: ANY("Movie")) If your filter blocks all results, the API returns 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 never returns Documents with storageStatus as 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 is 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 is returned in RecommendResponse.RecommendationResult.document. returnScore: Boolean. If set to true, the recommendation score corresponding to each returned Document is 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 returns 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. 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.

data_store_specs[]	DataStoreSpec Specs defining DataStores to filter on in a search call and configurations for those data stores. This is only considered for Engines with multiple data stores. For engines with a single data store, the specs directly under SearchRequest should be used.
filter	string The filter syntax consists of an expression language for constructing a predicate from one or more fields of the documents being filtered. Filter expression is case-sensitive. If this field is unrecognizable, an INVALID_ARGUMENT is returned. Filtering in Vertex AI Search is done by mapping the LHS filter key to a key property defined in the Vertex AI Search backend -- this mapping is defined by the customer in their schema. For example a media customer might have a field 'name' in their schema. In this case the filter would look like this: filter --> name:'ANY("king kong")' For more information about filtering including syntax and filter operators, see Filter
canonical_filter	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.
order_by	string The order in which documents are returned. Documents can be ordered by a field in an Document object. Leave it unset if ordered by relevance. order_by expression is case-sensitive. For more information on ordering the website search results, see Order web search results. For more information on ordering the healthcare search results, see Order healthcare search results. If this field is unrecognizable, an INVALID_ARGUMENT is returned.

language_code	string The BCP-47 language code, such as "en-US" or "sr-Latn". For more information, see Standard fields. This field helps to better interpret the query. If a value isn't specified, the query language code is automatically detected, which may not be accurate.
facet_specs[]	FacetSpec Facet specifications for faceted search. If empty, no facets are returned. A maximum of 100 values are allowed. Otherwise, an INVALID_ARGUMENT error is returned.
boost_spec	BoostSpec Boost specification to boost certain documents. For more information on boosting, see Boosting
params	map<string, Value> Additional search parameters. For public website search only, supported values are: user_country_code: string. Default empty. If set to non-empty, results are restricted or boosted based on the location provided. For example, user_country_code: "au" For available codes see Country Codes search_type: double. Default empty. Enables non-webpage searching depending on the value. The only valid non-default value is 1, which enables image searching. For example, search_type: 1
query_expansion_spec	QueryExpansionSpec The query expansion specification that specifies the conditions under which query expansion occurs.
spell_correction_spec	SpellCorrectionSpec The spell correction specification that specifies the mode under which spell correction takes effect.
user_pseudo_id	string 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 logs in or out of the website. This field should NOT have a fixed value such as unknown_visitor. This should be the same identifier as UserEvent.user_pseudo_id and CompleteQueryRequest.user_pseudo_id The field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.
content_search_spec	ContentSearchSpec A specification for configuring the behavior of content search.
safe_search	bool Whether to turn on safe search. This is only supported for website search.
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. 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 for more details.
search_as_you_type_spec	SearchAsYouTypeSpec Search as you type configuration. Only supported for the IndustryVertical.MEDIA vertical.
session	string The session resource name. Optional. Session allows users to do multi-turn /search API calls or coordination between /search API calls and /answer API calls. Example #1 (multi-turn /search API calls): 1. Call /search API with the auto-session mode (see below). 2. Call /search API with the session ID generated in the first call. Here, the previous search query gets considered in query standing. I.e., if the first query is "How did Alphabet do in 2022?" and the current query is "How about 2023?", the current query will be interpreted as "How did Alphabet do in 2023?". Example #2 (coordination between /search API calls and /answer API calls): 1. Call /search API with the auto-session mode (see below). 2. Call /answer API with the session ID generated in the first call. Here, the answer generation happens in the context of the search results from the first search call. Auto-session mode: when projects/.../sessions/- is used, a new session gets automatically created. Otherwise, users can use the create-session API to create a session manually. Multi-turn Search feature is currently at private GA stage. Please use v1alpha or v1beta version instead before we launch this feature to public GA. Or ask for allowlisting through Google Support team.
session_spec	SessionSpec Session specification. Can be used only when session is set.

BoostSpec

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.
boost_control_spec	BoostControlSpec Complex specification for custom ranking based on customer defined attribute value.

BoostControlSpec

Specification for custom ranking based on customer specified attribute value. It provides more controls for customized ranking than the simple (condition, boost) combination above.

Fields
field_name	string The name of the field whose value will be used to determine the boost amount.
attribute_type	AttributeType The attribute type to be used to determine the boost amount. The attribute value can be derived from the field value of the specified field_name. In the case of numerical it is straightforward i.e. attribute_value = numerical_field_value. In the case of freshness however, attribute_value = (time.now() - datetime_field_value).
interpolation_type	InterpolationType The interpolation type to be applied to connect the control points listed below.
control_points[]	ControlPoint The control points used to define the curve. The monotonic function (defined through the interpolation_type above) passes through the control points listed here.

AttributeType

The attribute(or function) for which the custom ranking is to be applied.

Enums
ATTRIBUTE_TYPE_UNSPECIFIED	Unspecified AttributeType.
NUMERICAL	The value of the numerical field will be used to dynamically update the boost amount. In this case, the attribute_value (the x value) of the control point will be the actual value of the numerical field for which the boost_amount is specified.
FRESHNESS	For the freshness use case the attribute value will be the duration between the current time and the date in the datetime field specified. The value must be formatted as an XSD dayTimeDuration value (a restricted subset of an ISO 8601 duration value). The pattern for this is: [nD][T[nH][nM][nS]]. For example, 5D, 3DT12H30M, T24H.

ControlPoint

The control points used to define the curve. The curve defined through these control points can only be monotonically increasing or decreasing(constant values are acceptable).

Fields
attribute_value	string Can be one of: 1. The numerical field value. 2. The duration spec for freshness: The value must be formatted as an XSD dayTimeDuration value (a restricted subset of an ISO 8601 duration value). The pattern for this is: [nD][T[nH][nM][nS]].
boost_amount	float The value between -1 to 1 by which to boost the score if the attribute_value evaluates to the value specified above.

InterpolationType

The interpolation type to be applied. Default will be linear (Piecewise Linear).

Enums
INTERPOLATION_TYPE_UNSPECIFIED	Interpolation type is unspecified. In this case, it defaults to Linear.
LINEAR	Piecewise linear interpolation will be 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.
summary_spec	SummarySpec If summarySpec is not specified, summaries are not included in the search response.
extractive_content_spec	ExtractiveContentSpec If there is no extractive_content_spec provided, there will be no extractive answer in the search response.
search_result_mode	SearchResultMode Specifies the search result mode. If unspecified, the search result mode defaults to DOCUMENTS.
chunk_spec	ChunkSpec Specifies the chunk spec to be returned from the search response. Only available if the SearchRequest.ContentSearchSpec.search_result_mode is set to CHUNKS

num_next_chunks	int32 The number of next chunks to be returned of the current chunk. The maximum allowed value is 3. If not specified, no next chunks will be returned.

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.
num_previous_segments	int32 Specifies whether to also include the adjacent from each selected segments. Return at most num_previous_segments segments before each selected segments.

reference_only (deprecated)	bool This item is deprecated! [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.
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.
ignore_low_relevant_content	bool Specifies whether to filter out queries that have low relevance. The default value is false. If this field is set to false, all search results are used regardless of relevance to generate answers. If set to true, only queries with high relevance search results will generate answers.
ignore_jail_breaking_query	bool Optional. Specifies whether to filter out jail-breaking queries. The default value is false. Google employs search-query classification to detect jail-breaking queries. No summary is returned if the search query is classified as a jail-breaking query. A user might add instructions to the query to change the tone, style, language, content of the answer, or ask the model to act as a different entity, e.g. "Reply in the tone of a competing company's CEO". If this field is set to true, we skip generating summaries for jail-breaking 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

For more information, see Answer generation model versions and lifecycle.

DataStoreSpec

A struct to define data stores to filter on in a search call and configurations for those data stores. Otherwise, an INVALID_ARGUMENT error is returned.

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 facet values that are returned for this facet. If unspecified, defaults to 20. The maximum allowed value is 300. Values above 300 are coerced to 300. For aggregation in healthcare search, when the [FacetKey.key] is "healthcare_aggregation_key", the limit will be overridden to 10,000 internally, regardless of the value set here. 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.

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.
engine	string The Engine resource name, in the form of projects/{project}/locations/{location}/collections/{collection_id}/engines/{engine_id}. Optional. Only required for Engine produced user events. For example, user events from blended search.
data_store	string The DataStore resource full name, of the form projects/{project}/locations/{location}/collections/{collection_id}/dataStores/{data_store_id}. Optional. Only required for user events whose data store can't by determined by UserEvent.engine or UserEvent.documents. If data store is set in the parent of write/import/collect user event requests, this field can be omitted.
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: If user has no activity for 30 min, a new session_id should be assigned. 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: RecommendResponse.attribution_token for events that are the result of RecommendationService.Recommend. SearchResponse.attribution_token for events that are the result of SearchService.Search. 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.
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.
panels[]	PanelInfo Optional. List of panels associated with this event. Used for page-level impression data.

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.
