Perhaps you should try some spelling variations:
de literatura » de litterature, la literatura, y literatura
studien beim » studie beim, studien die, studien am
filosofia de » filosofia del
texto scale » femto scale, texture scale, texto social
studien bei » studie bei

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "texto scale ((studien beim) OR (studien bei)) filosofia de literatura".
• Adding a wildcard symbol may retrieve word variants: texto scale ((studien beim) OR (studien bei)) filosofia de literatura*.
