【问题描述】：
我正在学习如何使用 Algolia，我有几个问题。
我有表 FreightDriver，它与表 Truck 有关系 one to many
id: ID!
name: String!
email: String!
phoneNumber: String!
cities: [String!]!
state: String!
country: String!
picture: String
trucks: [Truck] @connection(keyName: "byFreightDriver", fields: ["id"])
然后是表 Truck，它与表 FreightDriver 有关系 one to one，还有另一个表，即 Box one to one
id: ID!
freightDriverId: ID!
boxId: ID!
brand: String!
model: String!
yearModel: Int!
// and more fields
freightDriver: FreightDriver @connection(fields: ["freightDriverId"])
box: Box @connection(fields: ["boxId"])
和表框：
id: ID!
type: String!
width: Float!
height: Float!
depth: Float!
我想根据 FreightDrivers 所在的州和城市查找卡车，并且（如果用户需要）还根据卡车的箱子类型和品牌或型号查找（仅作为示例）。
按州和城市查找货运司机的示例：

}
}
但是，如果我想使用货运司机的州和城市、箱子的类型以及卡车的型号或品牌来查找，那就是问题所在，因为我使用的是 Dynamodb 而这个没有有关系，所以，获得准确的数据有点棘手。这就是我想使用 Algolia 的原因，但在这种情况下，如何格式化 Algolia 的数据？我需要做什么？谢谢！
