Hello friends,

Recently I needed to limit number of search results in haystack and that was a bit of a challenge. So I decided to share it with you here.

I knew how to limit search results using old style views (haystack.views.SearchView):

from haystack.views import SearchView

class MySearchView(SearchView):

    #limit maximum results
    def get_results(self):
        return self.form.search()[:100]

But at this time I needed to switch to new-style views (haystack.generic_views.SearchView), which use standard Django views. Obviously previous hack to limit results didn't work and I started brainstorming it by trying to override different methods, reading docs, etc. And finally I got this solution:

from haystack.generic_views import SearchView

class MySearchView(SearchView):

    template_name='search/search.html'
    #....

    def paginate_queryset(self, queryset, page_size):
        return super(MySearchView, self).paginate_queryset(queryset[:100], page_size)

The reason I'm using paginate_queryset is because it's the last method called to fetch the results from the db and thus we can do a slice. But if you have a better idea how to limit results, feel free to let me know.
