I'm following this example to setup Haystack with ES:https://krzysztofzuraw.com/blog/2016/haystack-elasticsearch-part-one.html
Everything seems to be working but for every search I do I get only up to 20 records as a result.
But actually there should be sometimes over 50 results.
I cannot find a setting neither for haystack nor for django which prevents showing more than 20 results.
So, where does this limitation come from? How can I change it?
