使用 mongoose 从数组中返回匹配的文档

Question

So basically i have a string of message and i want to get the document that matches the keyword

Tag to match: Time, Family

const sample_message = "This user have a challenge of Time and Family"

document_1 = {
challenge: Object ID 1
keywords: [ "Time", "Test" ]
}
document_2 = {
challenge: Object ID 2
keywords: [ "Family", "Test2" ]
}
document_3 = {
challenge: Object ID 3
keywords: [ "Foo", "Test3" ]
}



const result = model.find(keywords: { new Regexp(sample_message) })
console.log(result)

I need to return all the documents that match the keywords from sample_message which is the "Time" and "Family". Can someone explain the correct way?

Answer 1

db.model.find(
    {
        'keywords': {
            $elemMatch: {
                $elemMatch: {
                    $in: ['Time', 'Family']
                }
            }
        }
    },
    {
        "values.$": 1
    }
)
