Answer 1

¿Podría poner aquí su vista y su código de plantilla? Si esto sucede solo con algunas consultas y no con todas ellas, podrían ser los parámetros que está pasando a la vista. Aquí está el código de la opinión de que estoy usando para hacer consultas de búsqueda utilizando Haystack 2.0 y 2.3.2 Whoosh en un proyecto de mi propia:

def search(request): 
    sqs = SearchQuerySet().filter(content=AutoQuery(request.GET['q'])) 
return render_to_response('search.html', {'sqs': sqs,}) 

y esto funciona perfectamente bien. Supongo que deberías considerar usar la última versión de Haystack, porque estaba experimentando muchos errores con los viejos estables. Y te recomiendo que uses el "rebuild_index" de vez en cuando, por si acaso.
