e literatura » de literatura, y literatura, e literatur
e filosofia » la filosofia
best scale » rest scale, burst scale, best sales
bast scale » vast scale, basin scale, based scale

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: ((best scale) OR (bast scale)) student ((der filosofia) OR (e filosofia)) e literatura.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((best scale) or (bast scale)) student ((der filosofia) OR (e filosofia)) e literatura".
• Adding a wildcard symbol may retrieve word variants: ((best scale) or (bast scale)) student ((der filosofia) OR (e filosofia)) e literatura*.
