Question

I have a query to return posts and person content types.

var query = {
  type: {
    $in: ["post", "person"]
  },
}

But I only want to return person if person has any comments, but posts always.

var query = {
  type: {
    $in: ["post", "person"]
  },
  // somehow make this only for person
  // comments: {"$exists": true}
}

Is this possible or should I use map reduce?

Thanks.

Answer 1

var query = {
    $or: [
        { type: "post" },
        { type: "person", comments: { $exists: true }},
    ]
}
