Hey! Well, I see two ways of accomplishing that, one easy but not so good and another hard but a better solution.

The easy way is to just modify the Question model and add a "topic" field into it (it can either be a string or an array). The problem with that solution is that it can lead you to a lot of errors when registering new questions.

Now the second way is to create a model for the "topics" and modify the Question model with a new field for the "topics" (in this case, you would get the _id of the topic you want and save it inside the question). This way you can create new topics in the database and link them to the Questions.

It's kinda hard to explain how to do this with a comment, so I might write a new post to explain how you can build relationships between documents with mongodb as well. I hope I've been helpful.

true it's kinda hard to explain with a comment, maybe with code it'll be much clearer
