Perhaps you should try some spelling variations:
filosofica la » filosofica da, filosofia la, filosofia da
la literatura » la litterature, a literature
studien die » studie die
studien der » studie der, studenten der
best scale » bast scale, rest scale, burst scale

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: "best scale ((studien die) OR (studien der)) filosofica la literatura*".
