Perhaps you should try some spelling variations:
studies does » studies dress, studies ds, studies der
a literatura » la literatura, a literature, y literatura
studies doe » studies dose, studies do, studies die
filosofia a » filosofia da, filosofia la, filosofia e
basin » basic, basis

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: "basin scale ((studies doe) OR (studies does)) filosofia a literatura*".
