Python elasticsearch-dsl django pagination

Question

How can i use django pagination on elasticsearch dsl. My code:

query = MultiMatch(query=q, fields=[\'title\', \'body\'], fuzziness=\'AUTO\')

s = Search(usin

A very simple solution is to use MultipleObjectMixin and extract your Elastic results in get_queryset() by overriding it. In this case Django will take care of the pagination itself if you add the paginate_by attribute.

It should look like that:

class MyView(MultipleObjectMixin, ListView):
    paginate_by = 10

    def get_queryset(self):
        object_list = []
        """ Query Elastic here and return the response data in `object_list`.
            If you wish to add filters when querying Elastic,
            you can use self.request.GET params here. """
        return object_list

Note: The code above is broad and different from my own case so I can not guarantee it works. I used similar solution by inheriting other Mixins, overriding get_queryset() and taking advantage of Django's built in pagination - it worked great for me. As it was an easy fix I decided to post it here with a similar example.
