Perhaps you should try some spelling variations:
ve filosofiche » ve filosoficke, e filosofica, e filosofie
e filosofiche » ve filosoficke, e filosofica, e filosofie
lo literatura » la literatura, lo literatur, y literatura
test scale » tests scale, best scale, rest 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: "test scale study ((ve filosofiche) OR (e filosofiche)) lo literatura".
• Adding a wildcard symbol may retrieve word variants: test scale study ((ve filosofiche) OR (e filosofiche)) lo literatura*.
