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.

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 customers 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](https://cloud.google.com/generative-ai-app-builder/docs/filter-search-metadata)

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.

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 \> 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.

         * Performs a search. Similar to the SearchService.Search method, but a lite version that allows API key for authentication, where OAuth and IAM checks are not required. Only public website search is supported by this method. If data stores and engines not associated with public website search are specified, a `FAILED_PRECONDITION` error is returned. This method can be used for easy onboarding without having to implement an authentication backend. However, it is strongly recommended to use SearchService.Search instead with required OAuth and IAM checks to provide better data security.

         * Performs a search. Similar to the SearchService.Search method, but a lite version that allows API key for authentication, where OAuth and IAM checks are not required. Only public website search is supported by this method. If data stores and engines not associated with public website search are specified, a `FAILED_PRECONDITION` error is returned. This method can be used for easy onboarding without having to implement an authentication backend. However, it is strongly recommended to use SearchService.Search instead with required OAuth and IAM checks to provide better data security.

         * Performs a search. Similar to the SearchService.Search method, but a lite version that allows API key for authentication, where OAuth and IAM checks are not required. Only public website search is supported by this method. If data stores and engines not associated with public website search are specified, a `FAILED_PRECONDITION` error is returned. This method can be used for easy onboarding without having to implement an authentication backend. However, it is strongly recommended to use SearchService.Search instead with required OAuth and IAM checks to provide better data security.

        /**
         * Starts asynchronous cancellation on a long-running operation. The server makes a best effort to cancel the operation, but success is not guaranteed. If the server doesn't support this method, it returns `google.rpc.Code.UNIMPLEMENTED`. Clients can use Operations.GetOperation or other methods to check whether the cancellation succeeded or whether the operation completed despite cancellation. On successful cancellation, the operation is not deleted; instead, it becomes an operation with an Operation.error value with a google.rpc.Status.code of `1`, corresponding to `Code.CANCELLED`.
