Какой атрибут SearchQuerySet имеет ту же функцию, что и prefetch_related?

def get_books_by_query_params(context, query, query_parameters): binding_query = query_parameters['binding_query'] query_parameters['validate']=1 default_query = None if query: default_queries = [ Q(title__icontains=query), Q(isbn_10__contains=query), Q(isbn_13__contains=query), Q(publishers=Publisher.objects.filter(name=query)), Q(institutes=Institute.objects.filter(name=query)), Q(authors=Author.objects.filter(name=query)), Q(sellers=Seller.objects.filter(name=query)) ] default_query = reduce(operator.or_, default_queries) default_query = default_query & binding_query if binding_query is not None else default_query elif binding_query is not None: default_query = binding_query if default_query is not None and query_parameters['query_parameters'] is not None: books = Book.objects.filter(default_query, validate=1, **query_parameters['query_parameters']).distinct()\ .prefetch_related('authors').prefetch_related('publishers').prefetch_related('sellers').prefetch_related('institutes') elif query_parameters['query_parameters']: books = Book.objects.filter(validate=1,**query_parameters['query_parameters']).distinct()\ .prefetch_related('authors').prefetch_related('publishers').prefetch_related('sellers').prefetch_related('institutes') elif default_query: books = Book.objects.filter(default_query,validate=1).distinct().prefetch_related('authors').prefetch_related('publishers').prefetch_related('sellers').prefetch_related('institutes') else: books = Book.objects.filter(validate=1).distinct().prefetch_related('authors').prefetch_related('publishers').prefetch_related('sellers').prefetch_related('institutes') context['books'] = books return context 

Как написать следующий код с помощью searchqueryset? Есть ли эквивалент prefetch_related в наборе searchquery, который можно использовать в этом случае?
