Request message for SearchService.Search method.

Protobuf type google.cloud.retail.v2alpha.SearchRequest

Facet specifications for faceted search. If empty, no facets are returned.

A maximum of 200 values are allowed. Otherwise, an INVALID_ARGUMENT error is returned.

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).

The attributes from all the matching variant Products or LocalInventorys are merged and de-duplicated. Notice that rollup attributes will lead to extra query latency. Maximum number of keys is 30.

For FulfillmentInfo, a fulfillment type and a fulfillment ID must be provided in the format of "fulfillmentType.fulfillmentId". E.g., in "pickupInStore.store123", "pickupInStore" is fulfillment type and "store123" is the store ID.

Supported keys are:

• colorFamilies
• price
• originalPrice
• discount
• variantId
• inventory(place_id,price)
• inventory(place_id,original_price)
• inventory(place_id,attributes.key), where key is any key in the Product.local_inventories.attributes map.
