How to create a searchable API query to your AppSync service

Pre-req

This uses the schema from schema.graphql so you can go straight ahead into

1. amplify init

2. amplify add api and choose GraphQL, and use schema.graphql

3. amplify push

4. cd apiSearchableApp and run pod install

5. xed to open the app

Searchable query

The schema contains a model with @searchable annotated

type Blog6 @model @searchable {
  id: ID!
  name: String!
  posts: [Post6] @connection(keyName: "byBlog", fields: ["id"])
}

Run amplify console api and navigate to the Queries tab, and determine the search query you want to perform and its parameters.

This sample provides an extension that makes it easy to map to a AppSync search query.

func searchBlogs() {
    let filter: [String: Any] = [
        "name": [
            "matchPhrase": "first"
        ]
    ]
    Amplify.API.query(request: .search(Blog6.self,
                                        filter: filter,
                                        limit: 1000,
                                        sort: QuerySortBy.ascending(Blog6.keys.id))) { event in
        switch event {
        case .success(let result):
            switch result {
            case .success(let blogs):
                print("Successfully searched blogs: \(blogs)")
            case .failure(let error):
                print("Got failed result with \(error.errorDescription)")
            }
        case .failure(let error):
            print("Got failed event with error \(error)")
        }
    }
}
