Sort using MongoEngine?
Mongoengine is inspired by Django's ORM, and like Django, it uses order_by to sort the result set. order_by takes a variable number of string arguments, which are the field names (as defined in your documents) optionally preceded by a "-" (to indicate a descending sort, i.e. highest first).
For example:
class Person(Document): first_name = StringField() last_name = StringField() age = IntField()# laterpeople = Person.objects.order_by('last_name', '-age')
