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

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: basin scale ((studies doe) OR (((studies does) OR (studies der)))) filosofia a literatura*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "basin scale ((studies doe) or (((studies does) OR (studies der)))) filosofia a literatura*".
