The document says FaucetedSearch accept configuration option sort as a class attribute.

sort
tuple or list of fields on which the results should be sorted.

So I tried to create the following class.

class BlogSearch(FacetedSearch): index = 'blogs' doc_types = [Blog, Post] fields = ['title', 'content'] sort = ('-published_at',) def search(self): s = super().search() return s.filter('term', published=True)

Then it raises TypeError.

>>> BlogSearch().execute() Traceback (most recent call last): File "<console>", line 1, in <module> File "***/site-packages/elasticsearch_dsl/faceted_search.py", line 271, in __init__	self._s = self.build_search() File "***/site-packages/elasticsearch_dsl/faceted_search.py", line 381, in build_search	s = self.sort(s) TypeError: 'tuple' object is not callable 

I tried sort = '-publisehd_at' but got the same error. What kind of argument should be set?

BlogSearch(sort=('-published_at',)) works fine, but I'd like to set the default sort order.
