Request message for DocumentService.SearchDocuments.

Attributes

• documentQuery (type: GoogleApi.ContentWarehouse.V1.Model.GoogleCloudContentwarehouseV1DocumentQuery.t, default: nil) - Query used to search against documents (keyword, filters, etc.).
• histogramQueries (type: list(GoogleApi.ContentWarehouse.V1.Model.GoogleCloudContentwarehouseV1HistogramQuery.t), default: nil) - An expression specifying a histogram request against matching documents. Expression syntax is an aggregation function call with histogram facets and other options. The following aggregation functions are supported: count(string_histogram_facet): Count the number of matching entities for each distinct attribute value. Data types: Histogram facet (aka filterable properties): Facet names with format <schema id>.<facet>. Facets will have the format of: a-zA-Z. If the facet is a child facet, then the parent hierarchy needs to be specified separated by dots in the prefix after the schema id. Thus, the format for a multi- level facet is: <schema id>.<parent facet name>. <child facet name>. Example: schema123.root_parent_facet.middle_facet.child_facet DocumentSchemaId: (with no schema id prefix) to get histograms for each document type (returns the schema id path, e.g. projects/12345/locations/us-west/documentSchemas/abc123). Example expression: Document type counts: count('DocumentSchemaId') * For schema id, abc123, get the counts for MORTGAGE_TYPE: count('abc123.MORTGAGE_TYPE')
• offset (type: integer(), default: nil) - An integer that specifies the current offset (that is, starting result location, amongst the documents deemed by the API as relevant) in search results. This field is only considered if page_token is unset. The maximum allowed value is 5000. Otherwise an error is thrown. For example, 0 means to return results starting from the first matching document, and 10 means to return from the 11th document. This can be used for pagination, (for example, pageSize = 10 and offset = 10 means to return from the second page).
• orderBy (type: String.t, default: nil) - The criteria determining how search results are sorted. For non-empty query, default is "relevance desc". For empty query, default is "upload_date desc". Supported options are: "relevance desc": By relevance descending, as determined by the API algorithms. "upload_date desc": By upload date descending. "upload_date": By upload date ascending. "update_date desc": By last updated date descending. "update_date": By last updated date ascending. "retrieval_importance desc": By retrieval importance of properties descending. This feature is still under development, please do not use unless otherwise instructed to do so.
• pageSize (type: integer(), default: nil) - A limit on the number of documents returned in the search results. Increasing this value above the default value of 10 can increase search response time. The value can be between 1 and 100.
• pageToken (type: String.t, default: nil) - The token specifying the current offset within search results. See SearchDocumentsResponse.next_page_token for an explanation of how to obtain the next set of query results.
• qaSizeLimit (type: integer(), default: nil) - Experimental, do not use. The limit on the number of documents returned for the question-answering feature. To enable the question-answering feature, set [DocumentQuery].is_nl_query to true.
• requestMetadata (type: GoogleApi.ContentWarehouse.V1.Model.GoogleCloudContentwarehouseV1RequestMetadata.t, default: nil) - The meta information collected about the end user, used to enforce access control and improve the search quality of the service.
• requireTotalSize (type: boolean(), default: nil) - Controls if the search document request requires the return of a total size of matched documents. See SearchDocumentsResponse.total_size. Enabling this flag may adversely impact performance. Hint: If this is used with pagination, set this flag on the initial query but set this to false on subsequent page calls (keep the total count locally). Defaults to false.
• totalResultSize (type: String.t, default: nil) - Controls if the search document request requires the return of a total size of matched documents. See SearchDocumentsResponse.total_size.
