Perhaps you should try some spelling variations:
la literatura » la litterature, a literature
filosofia la » filosofia da, filosofia le, filosofica da
texto scale » femto scale, texture scale, texto social
studien die » studie die
studien der » studie der, studenten der

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 ((studien die) OR (studien der)) filosofia la literatura.
• Adding a wildcard symbol may retrieve word variants: texto scale ((studien die) or (studien der)) filosofia la literatura*.
