Graphql 如何使用AWS Amplify搜索@连接

因此，我的模式中有3个集合

type User @model(subscriptions: null)  {
  id: ID!
  name: String
  email: String
  events: [EventUser] @connection(keyName: "byUser", fields: ["id"])
}

我正试图通过

eventID

和

user.name

搜索

EventUser

集合。是否有一些放大功能可以让我通过

user.name

搜索并返回

EventUser

集合

type Event @model
  @key(name: "byApiKey", fields: ["apiKey"])
  @key(name: "byOrganization", fields: ["organizationID"], queryField: "eventByOrganization")
  {
  id: ID!
  apiKey: ID!
  title: String
  participants: [EventUser] @connection(keyName: "byEvent", fields: ["id"])
}

type EventUser @model
  @key(name: "byUser", fields: ["userID"], queryField: "eventByUser")
  @key(name: "byEvent", fields: ["eventID"], queryField: "userByEvent")    {
  id: ID!
  userID: ID!
  eventID: ID!
  user: User! @connection(fields: ["userID"])
  event: Event! @connection(fields: ["eventID"])
}
