      Assume the collection name "groups"

      Sample Document:

      {
    "_id" : ObjectId("597620fcba76f211586c9203"),
    "task" : {
        "taskId" : ObjectId("597620fcba76f211586c9402"),
        "hasTasks" : true
    }
}

      Failing Query:

      db.getCollection('groups').find({task: { hasTasks: true, taskId: ObjectId("597620fcba76f211586c9402")}, _id: ObjectId("597620fcba76f211586c9203") })

      Passing Query:

      db.getCollection('groups').find({task: { taskId: ObjectId("597620fcba76f211586c9402"), hasTasks: true, }, _id: ObjectId("597620fcba76f211586c9203") })

      As you can see, if the order of the query fields in the sub-document (viz. task) does not match the order in which it exists in the document, query does not return any results.
