使用React本机创建GraphQL搜索查询

Question

我试图实现一个搜索查询，以帮助我搜索的名称或类别。我只需要帮助它的后端部分，即设置解析器和索引，我不确定我是否做得对。

Resolver.js

//search for single user
    user: async ({_id}) => {
        try {
            const foundUser = await User.findOne({_id: _id})
            return foundUser;
        } catch (err){
            throw err;
        }
    },
//search for all users
    users: async () => {
        try{
            const users = await User.find()
            return users;
        } catch(err) {
            throw err;
        }
    },

我想要能够搜索所有的角色“明星”的用户，并且只对那些用户进行搜索。不太确定从这里往哪里走，Index.js

type User {
    _id: ID!
    username: String
    password: String
    name: String
    role: String
    enterCategory: String
}
//not sure if search is right
type RootQuery {
    user(_id: ID!): User!
    users: [User!]!
    searchStars(search: String): [Users]!
}

Answer 1

Index.js

    searchCategories(search: String): [User]!

Resolver

 searchCategories: async ({ search }) => {
        try {
            const users = await User.find()
            return users.filter(x => x.enterCat === search);
        } catch (err) {
            throw err;
        }
    }
