Mongoose Like Operator

Question

下面的代码不起作用并返回一个空数组。有什么问题：

const user = mongoose.model('user', {
    firstName: String
});

async function usersBySearch(search) {
    return await user.find({firstName: '/' + search + "/"});
};

Answer 1

您应该使用$regex

user.find( { 'firstName' : { '$regex' : search, '$options' : 'i' } } )

where options：我将进行不区分大小写的匹配
