Perhaps you should try some spelling variations:
de literatura » de litterature, y literatura, a literatura
la literatura » la litterature, a literature
em filosofia » e filosofia, la filosofia, di filosofia
quito scale » equity scale
auto scale » auto scaled, auto scaler, auto escape
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: ((quito scale) OR (auto scale)) studien em filosofia ((de literatura) OR (la literatura)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((quito scale) or (auto scale)) studien em filosofia ((de literatura) OR (la literatura))".
• Adding a wildcard symbol may retrieve word variants: ((quito scale) or (auto scale)) studien em filosofia ((de literatura) OR (la literatura))*.
