A `binding` binds one or more `members`, or principals, to a single `role`. Principals can be user accounts, service accounts, Google groups, and domains (such as G Suite). A `role` is a named list of permissions; each `role` can be an IAM predefined role or a user-created custom role. For some types of Google Cloud resources, a `binding` can also specify a `condition`, which is a logical expression that allows access to a resource only if the expression evaluates to `true`. A condition can add constraints based on attributes of the request, the resource, or both. To learn which resources support conditions in their IAM policies, see the [IAM documentation](https://cloud.google.com/iam/help/conditions/resource-policies). **JSON example:** ``` { \"bindings\": [ { \"role\": \"roles/resourcemanager.organizationAdmin\", \"members\": [ \"user:mike@example.com\", \"group:admins@example.com\", \"domain:google.com\", \"serviceAccount:my-project-id@appspot.gserviceaccount.com\" ] }, { \"role\": \"roles/resourcemanager.organizationViewer\", \"members\": [ \"user:eve@example.com\" ], \"condition\": { \"title\": \"expirable access\", \"description\": \"Does not grant access after Sep 2020\", \"expression\": \"request.time \u003c timestamp('2020-10-01T00:00:00.000Z')\", } } ], \"etag\": \"BwWWja0YfJA=\", \"version\": 3 } ``` **YAML example:** ``` bindings: - members: - user:mike@example.com - group:admins@example.com - domain:google.com - serviceAccount:my-project-id@appspot.gserviceaccount.com role: roles/resourcemanager.organizationAdmin - members: - user:eve@example.com role: roles/resourcemanager.organizationViewer condition: title: expirable access description: Does not grant access after Sep 2020 expression: request.time \u003c timestamp('2020-10-01T00:00:00.000Z') etag: BwWWja0YfJA= version: 3 ``` For a description of IAM and its features, see the [IAM documentation](https://cloud.google.com/iam/docs/).",

Each occurrence of a principal counts towards these limits.

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.",

Example ranking expression: If document has an embedding field doc_embedding, the ranking expression could be `0.5 * relevance_score + 0.3 * dotProduct(doc_embedding)`. If ranking_expression_backend is set to `RANK_BY_FORMULA`, the following expression types (and combinations of those chained using + or * operators) are supported: * `double` * `signal` * `log(signal)` * `exp(signal)` * `rr(signal, double \u003e 0)` -- reciprocal rank transformation with second argument being a denominator constant. * `is_nan(signal)` -- returns 0 if signal is NaN, 1 otherwise. * `fill_nan(signal1, signal2 | double)` -- if signal1 is NaN, returns signal2 | double, else returns signal1. Here are a few examples of ranking formulas that use the supported ranking expression types: - `0.2 * semantic_similarity_score + 0.8 * log(keyword_similarity_score)` -- mostly rank by the logarithm of `keyword_similarity_score` with slight `semantic_smilarity_score` adjustment. - `0.2 * exp(fill_nan(semantic_similarity_score, 0)) + 0.3 * is_nan(keyword_similarity_score)` -- rank by the exponent of `semantic_similarity_score` filling the value with 0 if it's NaN, also add constant 0.3 adjustment to the final score if `semantic_similarity_score` is NaN. - `0.2 * rr(semantic_similarity_score, 16) + 0.8 * rr(keyword_similarity_score, 16)` -- mostly rank by the reciprocal rank of `keyword_similarity_score` with slight adjustment of reciprocal rank of `semantic_smilarity_score`. The following signals are supported: * `semantic_similarity_score`: semantic similarity adjustment that is calculated using the embeddings generated by a proprietary Google model. This score determines how semantically similar a search query is to a document. * `keyword_similarity_score`: keyword match adjustment uses the Best Match 25 (BM25) ranking function. This score is calculated using a probabilistic model to estimate the probability that a document is relevant to a given query. * `relevance_score`: semantic relevance adjustment that uses a proprietary Google model to determine the meaning and intent behind a user's query in context with the content in the documents. * `pctr_rank`: predicted conversion rate adjustment as a rank use predicted Click-through rate (pCTR) to gauge the relevance and attractiveness of a search result from a user's perspective. A higher pCTR suggests that the result is more likely to satisfy the user's query and intent, making it a valuable signal for ranking. * `freshness_rank`: freshness adjustment as a rank * `document_age`: The time in hours elapsed since the document was last updated, a floating-point number (e.g., 0.25 means 15 minutes). * `topicality_rank`: topicality adjustment as a rank. Uses proprietary Google model to determine the keyword-based overlap between the query and the document. * `base_rank`: the default rank of the result * `media_actor_match`: whether the media actor matches the query * `media_director_match`: whether the media director matches the query * `media_genre_match`: whether the media genre matches the query * `media_language_match`: whether the media language matches the query * `media_title_match`: whether the media title matches the query * `media_prefix_similarity_rank`: prefix similarity rank for media results * `media_semantic_similarity_rank`: semantic similarity rank for media results"

If ranking_expression_backend is not provided or set to `RANK_BY_EMBEDDING`, it should be a single function or multiple functions that are joined by \"+\". * ranking_expression = function, { \" + \", function }; Supported functions: * double * relevance_score * double * dotProduct(embedding_field_path) Function variables: * `relevance_score`: pre-defined keywords, used for measure relevance between query and document. * `embedding_field_path`: the document embedding field used with query embedding vector. * `dotProduct`: embedding function between `embedding_field_path` and query embedding vector. Example ranking expression: If document has an embedding field doc_embedding, the ranking expression could be `0.5 * relevance_score + 0.3 * dotProduct(doc_embedding)`. If ranking_expression_backend is set to `RANK_BY_FORMULA`, the following expression types (and combinations of those chained using + or * operators) are supported: * `double` * `signal` * `log(signal)` * `exp(signal)` * `rr(signal, double \u003e 0)` -- reciprocal rank transformation with second argument being a denominator constant. * `is_nan(signal)` -- returns 0 if signal is NaN, 1 otherwise. * `fill_nan(signal1, signal2 | double)` -- if signal1 is NaN, returns signal2 | double, else returns signal1. Here are a few examples of ranking formulas that use the supported ranking expression types: - `0.2 * semantic_similarity_score + 0.8 * log(keyword_similarity_score)` -- mostly rank by the logarithm of `keyword_similarity_score` with slight `semantic_smilarity_score` adjustment. - `0.2 * exp(fill_nan(semantic_similarity_score, 0)) + 0.3 * is_nan(keyword_similarity_score)` -- rank by the exponent of `semantic_similarity_score` filling the value with 0 if it's NaN, also add constant 0.3 adjustment to the final score if `semantic_similarity_score` is NaN. - `0.2 * rr(semantic_similarity_score, 16) + 0.8 * rr(keyword_similarity_score, 16)` -- mostly rank by the reciprocal rank of `keyword_similarity_score` with slight adjustment of reciprocal rank of `semantic_smilarity_score`. The following signals are supported: * `semantic_similarity_score`: semantic similarity adjustment that is calculated using the embeddings generated by a proprietary Google model. This score determines how semantically similar a search query is to a document. * `keyword_similarity_score`: keyword match adjustment uses the Best Match 25 (BM25) ranking function. This score is calculated using a probabilistic model to estimate the probability that a document is relevant to a given query. * `relevance_score`: semantic relevance adjustment that uses a proprietary Google model to determine the meaning and intent behind a user's query in context with the content in the documents. * `pctr_rank`: predicted conversion rate adjustment as a rank use predicted Click-through rate (pCTR) to gauge the relevance and attractiveness of a search result from a user's perspective. A higher pCTR suggests that the result is more likely to satisfy the user's query and intent, making it a valuable signal for ranking. * `freshness_rank`: freshness adjustment as a rank * `document_age`: The time in hours elapsed since the document was last updated, a floating-point number (e.g., 0.25 means 15 minutes). * `topicality_rank`: topicality adjustment as a rank. Uses proprietary Google model to determine the keyword-based overlap between the query and the document. * `base_rank`: the default rank of the result * `media_actor_match`: whether the media actor matches the query * `media_director_match`: whether the media director matches the query * `media_genre_match`: whether the media genre matches the query * `media_language_match`: whether the media language matches the query * `media_title_match`: whether the media title matches the query * `media_prefix_similarity_rank`: prefix similarity rank for media results * `media_semantic_similarity_rank`: semantic similarity rank for media results"

If ranking_expression_backend is not provided or set to `RANK_BY_EMBEDDING`, it should be a single function or multiple functions that are joined by \"+\". * ranking_expression = function, { \" + \", function }; Supported functions: * double * relevance_score * double * dotProduct(embedding_field_path) Function variables: * `relevance_score`: pre-defined keywords, used for measure relevance between query and document. * `embedding_field_path`: the document embedding field used with query embedding vector. * `dotProduct`: embedding function between `embedding_field_path` and query embedding vector. Example ranking expression: If document has an embedding field doc_embedding, the ranking expression could be `0.5 * relevance_score + 0.3 * dotProduct(doc_embedding)`. If ranking_expression_backend is set to `RANK_BY_FORMULA`, the following expression types (and combinations of those chained using + or * operators) are supported: * `double` * `signal` * `log(signal)` * `exp(signal)` * `rr(signal, double \u003e 0)` -- reciprocal rank transformation with second argument being a denominator constant. * `is_nan(signal)` -- returns 0 if signal is NaN, 1 otherwise. * `fill_nan(signal1, signal2 | double)` -- if signal1 is NaN, returns signal2 | double, else returns signal1. Here are a few examples of ranking formulas that use the supported ranking expression types: - `0.2 * semantic_similarity_score + 0.8 * log(keyword_similarity_score)` -- mostly rank by the logarithm of `keyword_similarity_score` with slight `semantic_smilarity_score` adjustment. - `0.2 * exp(fill_nan(semantic_similarity_score, 0)) + 0.3 * is_nan(keyword_similarity_score)` -- rank by the exponent of `semantic_similarity_score` filling the value with 0 if it's NaN, also add constant 0.3 adjustment to the final score if `semantic_similarity_score` is NaN. - `0.2 * rr(semantic_similarity_score, 16) + 0.8 * rr(keyword_similarity_score, 16)` -- mostly rank by the reciprocal rank of `keyword_similarity_score` with slight adjustment of reciprocal rank of `semantic_smilarity_score`. The following signals are supported: * `semantic_similarity_score`: semantic similarity adjustment that is calculated using the embeddings generated by a proprietary Google model. This score determines how semantically similar a search query is to a document. * `keyword_similarity_score`: keyword match adjustment uses the Best Match 25 (BM25) ranking function. This score is calculated using a probabilistic model to estimate the probability that a document is relevant to a given query. * `relevance_score`: semantic relevance adjustment that uses a proprietary Google model to determine the meaning and intent behind a user's query in context with the content in the documents. * `pctr_rank`: predicted conversion rate adjustment as a rank use predicted Click-through rate (pCTR) to gauge the relevance and attractiveness of a search result from a user's perspective. A higher pCTR suggests that the result is more likely to satisfy the user's query and intent, making it a valuable signal for ranking. * `freshness_rank`: freshness adjustment as a rank * `document_age`: The time in hours elapsed since the document was last updated, a floating-point number (e.g., 0.25 means 15 minutes). * `topicality_rank`: topicality adjustment as a rank. Uses proprietary Google model to determine the keyword-based overlap between the query and the document. * `base_rank`: the default rank of the result * `media_actor_match`: whether the media actor matches the query * `media_director_match`: whether the media director matches the query * `media_genre_match`: whether the media genre matches the query * `media_language_match`: whether the media language matches the query * `media_title_match`: whether the media title matches the query * `media_prefix_similarity_rank`: prefix similarity rank for media results * `media_semantic_similarity_rank`: semantic similarity rank for media results"
