Perhaps you should try some spelling variations:
de literatura » de litterature, la literatura, y literatura
texto social » text social, texts social, texas social
em filosofia » e filosofia, la filosofia, di filosofia
filosofia de » filosofia del
texto scale » texture scale
studien em » studien am, studien es, studien beim

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

• If you are trying to use Boolean operators, they must be ALL CAPS: ((((texto scale) OR (femto scale))) OR (texto social)) studien em filosofia de literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((((texto scale) OR (femto scale))) or (texto social)) studien em filosofia de literatura".
• Adding a wildcard symbol may retrieve word variants: ((((texto scale) OR (femto scale))) or (texto social)) studien em filosofia de literatura*.
