}

Fields
`branch`	`string` Required. The branch resource name, such as `projects/*/locations/global/catalogs/default_catalog/branches/0`. Use "default_branch" as the branch ID or leave this field empty, to search products under the default branch.
`query`	`string` Optional. Raw search query to be searched for. If this field is empty, the request is considered a category browsing request.
`pageCategories[]`	`string` Optional. The categories associated with a category page. Must be set for category navigation queries to achieve good search quality. The format should be the same as `UserEvent.page_categories`; To represent full path of category, use '>' sign to separate different hierarchies. If '>' is part of the category name, replace it with other character(s). Category pages include special pages such as sales or promotions. For instance, a special sale page may have the category hierarchy: "pageCategories" : ["Sales > 2017 Black Friday Deals"].
`conversationId`	`string` Optional. This field specifies the conversation id, which maintains the state of the conversation between client side and server side. Use the value from the previous `ConversationalSearchResponse.conversation_id`. For the initial request, this should be empty.
`searchParams`	`object (SearchParams)` Optional. servingConfigs.search parameters.
`visitorId`	`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 logs in or out of the website. This should be the same identifier as `UserEvent.visitor_id`. The field must be a UTF-8 encoded string with a length limit of 128 characters. Otherwise, an INVALID_ARGUMENT error is returned.
`userInfo`	`object (UserInfo)` Optional. User information.
`conversationalFilteringSpec`	`object (ConversationalFilteringSpec)` Optional. This field specifies all conversational filtering related parameters.
`userLabels`	`map (key: string, value: string)` Optional. 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.
`safetySettings[]`	`object (SafetySetting)` Optional. The safety settings to be applied to the generated content.
`suggestConversationQuery`	`boolean` Optional. If set to true, the service will suggest conversation queries based on the user query.

Response body

If successful, the response body contains a stream of ConversationalSearchResponse instances.
